Note: In order to ensure that the boot mode is correctly captured, the application needs to apply the valid boot mode value the entire time that RESET is asserted.
RESET can be asserted as a consequence of the internal reset generation. This will force re-sampling of the boot mode pins. (See Table 9-12 for details.)

In Table 13-3 (RTCC field descriptions), update the Note in the RTCC[APIVAL] field description:
Note: API functionality starts only when APIVAL is nonzero. The first API interrupt takes two more cycles because of synchronization of APIVAL to the RTC cloc k, and APIVAL + 1 cycles for subsequent occurrences. After that, interrupts are periodic in nature. Because of synchronization issues, the minimum supported value of APIVAL is 4.

Replace Section 16.5.8, Dynamic programming, with the following:
16.5.8 Dynamic programming
16.5.8.1
Dynamic channel linking is the process of setting the TCD.major.e_link bit during channel execution. This bit is read from the TCD local memory at the end of channel execution, thus allowing the user to enable the feature during channel execution.
Because the user is allowed to change the configuration during execution, a coherency model is needed. Consider the scenario where the user attempts to execute a dynamic channel link by enabling the TCD.major.e_link bit at the same time the eDMA engine is retiring the channel. The TCD.major.e_link would be set in the programmer’s model, but it would be unclear whether the actual link was made before the channel retired.
The coherency model in Table 16-24 is recommended when executing a dynamic channel link request.
Dynamic channel linking
For this request, the TCD local memory controller forces the TCD.major .e_link bit to zero on any writes to a channel’s TCD.word7 after that channel’s TCD.done bit is set, indicating the major loop is complete.
Freescale Semiconductor 3
NOTE
The user must clear the TCD.done bit before writing the TCD.major .e_link bit. The TCD.done bit is cleared automatically by the eDMA engine after a channel begins execution.

16.5.8.2 Dynamic scatter/gather
Dynamic scatter/gather is the process of setting the TCD.e_sg bit during channel execution. This bit is read from the TCD local memory at the end of channel execution, thus allowing the user to enable the feature during channel execution.
Because the user is allowed to change the configuration during execution, a coherency model is needed. Consider the scenario where the user attempts to execute a dynamic scatter/gather operation by enabling the TCD.e_sg bit at the same time the eDMA engine is retiring the channel. The TCD.e_sg would be set in the programmer’s model, but it would be unclear whether the actual scatter/gather request was honored before the channel retired.
T wo methods for this coherency model are shown in the following subsections. Method 1 has the advantage of reading the major.linkch field and the e_sg bit with a single read. For both dynamic channel linking and scatter/gather requests, the TCD local memory controller forces the TCD.major.e_link and TCD.e_sg bits to zero on any writes to a channel’ s TCD.word7 if that channel’ s TCD.done bit is set indicating the major loop is complete.
NOTE
The user must clear the TCD.done bit before writing the TCD.major .e_link or TCD.e_sg bits. The TCD.done bit is cleared automatically by the eDMA engine after a channel begins execution.
16.5.8.2.1 Method 1 (channel not using major loop channel linking)
For a channel not using major loop channel linking, the coherency model in
Table 16-25 may be used for a dynamic scatter/gather request.
When the TCD.major .e_link bit is zero, the TCD.major.linkch field is not used by the eDMA. In this case, the TCD.major.linkch bits may be used for other purposes. This method uses the TCD.major .linkch field as a TCD identification (ID).

Table 16-25. Coherency model for method 1
Step Action
1 When the descriptors are built, write a unique TCD ID in the TCD .major .linkch field for
each TCD associated with a channel using dynamic scatter/gather.
2 Write 1b to theTCD.d_req bit.
Note: Should a dynamic scatter/gather attempt fail, setting the d_req bit will prevent a
future hardware activation of this channel. This stops the channel from executing with a destination address (daddr) that was calculated using a scatter/gather address (written in the next step) instead of a dlast final offset
value. 3 Write theTCD.dlast_sga field with the scatter/gather address. 4 Write 1b to the TCD.e_sg bit. 5 Read back the 16 bit TCD control/status field. 6 Test the TCD.e_sg request status and TCD.major.linkch value:
• If e_sg = 1b, the dynamic link attempt was successful.
• If e_sg = 0b and the major.linkch (ID) did not change, the attempted dynamic link did not succeed (the channel was already retiring).
• If e_sg = 0b and the major.linkch (ID) changed, the dynamic link attempt was successful (the new TCD’s e_sg value cleared the e_sg bit).

16.5.8.2.2 Method 2 (channel using major loop linking)
For a channel using major loop channel linking, the coherency model in
Table 16-26 may be used for a dynamic scatter/gather request. This method
uses the TCD.dlast_sga field as a TCD identification (ID). For a channel using major loop channel linking, the coherency model in
Table 16-26 may be used for a dynamic scatter/gather request. This method
uses the TCD.dlast_sga field as a TCD identification (ID).

• If e_sg = 1b, the dynamic link attempt was successful.
• If e_sg = 0b, read the 32 bit TCD dlast_sga field.
• If e_sg = 0b and the dlast_sga did not change, the attempted dynamic link did not succeed (the channel was already retiring).
• If e_sg = 0b and the dlast_sga changed, the dynamic link attempt was successful (the new TCD’s e_sg value cleared the e_sg bit).

23.8.2.1.6 Overrun
Once the message buffer is full, the next valid message reception leads to an
overrun and a message is lost. The hardware sets the BOF bit in the LINSR to
signal the overrun condition. Which message is lost depends on the
configuration of the RX message buffer:
• If the buffer lock function is disabled (LINCR1[RBLM] = 0) the last message stored in the buffer is overwritten by the new incoming message. In this case the latest message is always available to the application.
• If the buffer lock function is enabled (LINCR1[RBLM] = 0) the most recent message is discarded and the previous message is available in the buffer.

Remove references throughout the chapter to “low-cost MCUs.”
Remove Note: above Table 25-2:
Note: The individual Rx Mask per Message Buffer feature may not be available in low cost MCUs. Please consult the specific MCU documentation to find out if this feature is supported. If not supported, the address range 0x0880-0x097F is considered reserved space, independent of the value of the BCC bit.
Added this Note in the RTR field description of Table 25-4 (Message Buffer Structure field
description):
Note: Do not configure the last Message Buffer to be the RTR frame.
Remove Note: in Section 25.4.4.13 Rx Individual Mask Registers (RXIMR0–RXIMR63):
Note: The individual Rx Mask per Message Buffer feature may not be available in low cost MCUs. Please consult the specific MCU documentation to find out if this feature is supported. If not supported, the RXGMASK, RX14MASK and RX15MASK registers are available, regardless of the value of the BCC bit.
Remove Note: at end of Section 25.5.6, Matching process:
Note: The individual Rx Mask per Message Buffer feature may not be available in low cost MCUs. Please consult the specific MCU documentation to find out if this feature is supported. If not supported, the RXGMASK, RX14MASK, and RX15MASK registers are available, regardless of the value of the BCC bit.
In Section 25.5.9.4, Protocol timing, update the Note following Figure 25-16 (CAN Engine
Clocking Scheme) to read: “This clock selection feature may not be available in all MCUs. A
particular MCU may not have a PLL, in which case it would have only the oscillator clock, or it may use only the PLL clock feeding the FlexCAN module. In these cases, the CLK_SRC bit in the CTRL Register has no effect on the module operation.”
Update the table title of Table 25-22 from “CAN Standard Compliant Bit Time Segment Settings”
to “Bosch CAN 2.0B standard compliant bit time segment settings.”

In Section 25.5.9.4, Protocol timing, update the Note following Table 25-22 to read: “Other
combinations of Time Segment 1 and Time Segment 2 can be valid. It is the user’s responsibility to ensure the bit time settings are in compliance with the CAN standard. For bit time calculations, use an IPT (Information Processing Time) of 2, which is the value implemented in the FlexCAN module.”
In Section 28.3.4.2, CTU in trigger mode, replace the sentence: If another CTU conversion is triggered before the end of the conversion, that request is
discarded.
with:
If another CTU conversion is triggered before the end of the conversion, that request is discarded. However, if the CTU has triggered a conversion that is still ongoing on a channel, it will buffer a second request fo r the channel and wait for the end of the first conv ersion before requesting another conversion. Thus, two conversion requests close together will both be serviced.
In Section 28.3.5.2, Presampling channel enable signals, in Table 28-7, Presampling voltage
selection based on PREVALx fields, in the 01 row, change the “Presampling voltage” field to:
V1 = V
DD_HV_ADC0
or V
DD_HV_ADC1

Add Note to Section 28.3.11, Auto-clock-off mode:
Note: The auto-clock-off feature cannot operate when the digital interface runs at the same rate as the analog interface. This means that when MCR.ADCCLKSEL = 1, the analog clock will not shut down in IDLE mode.
At the end of Section 29.4.1, Event Configuration Registers (CTU_EVTCFGRx) (x = 0...63), add
the following Note:
NOTE
The CTU tracks issued conversion requests to the ADC. When the ADC is being triggered by the CTU and there is a need to shut down the ADC, the ADC must be allowed to complete conversions before being shut down. This ensures that the CTU is notified of completion; if the ADC is shut down while performing a CTU-triggered conversion, the CTU is not notified and will not be able to trigger further conversions until the device is reset.
