2 D9 AAN50_PQB6 See AAN48_PQB4
4 B9 AAN49_PQB5 See AAN48_PQB4
6 A9 AAN48_PQB4
Analog input channel: passed on as a separate signal to the QADC.
Port (PQB): has a synchronizer with an input enable and clock.
8 B8 AAN3_PQB3 See AAN0_PQB0
10 C8 AAN2_PQB2 See AAN0_PQB0
12 See AAN0_PQB0
14 A8 AAN0_PQB0
Multiplexed input analog channel: passed on as a
separate signal to the QADC.
21 A17 MDA11
Double action: provide a path for two 16-bit input captures
and two 16-bit output captures.

30 W20 /HRESETB
Hard reset: after negation of /HRESET is detected, a 16-cycle period is
taken before testing an external reset. An external pull-up device is
required to negate /HRESET.
31 C16 ETRIG1
External trigger input to the QADC_A and QADC_B modules.
Can be configured for both QADC_A and QADC_B.
32 U18 EXTCLK
External frequency source for the chip.
Must be grounded if unused.
33 B16 ETRIG2 See ETRIG1
34 N4 /BBB_IWP3
Bus busy: master is using the bus.
Visible instruction queue flush status.
Load/store watchpoint. 3
35 U4 /BDIPB Burst data in progress : in dic ate s that a data beat follows the current one.
36 N3 /BGB_LWP1
Bus grant: indicates external data bus status. Visible instruction
queue flush status Load/store watchpoint
37 V2 /BIB_/STSB
Burst inhibit: ”0” → slave device is not able to support burst transfers.
Special transfer start: beginning of an internal transaction in showcycle
mode.
38 N2 /BRB_IWP2
Bus request: the data bus has been requested for external cycle.
Visible instruction queue flush status Load/store watchpoint 2
39 V1 /BURSTB Burst indicator: ”0” → burst transaction
40 M4 SGP_/IRQOUTB SGPIO, interrupt out: an interrupt has been sent to external devices.
41 U3 /TSB Transfer start: start of a bus cycle that transfers data
42 P18 EPEE Input: will externally control the program or erase operations.
47 M19 ECK External bus clock (EBCK): external baud clock used by SCI1 and SCI2
48 U19 ENGCLK/BUCLK
ENGCLK: engineering clock output. Full strength, half strength, dis abled.
Using EECLK[0:1] bits in the SCCR register.
BUCLK: backup clock, less precise on-chip ring oscillator for minimum
functionality.
49 N17 RXD1_QGPI Receive data: serial input from the SCI1
50 N18 TXD1_QGPO Transmit data: serial output from the SCI1
51 N19 RXD2_QGPI Receive data: serial input from the SCI2
52 N20 TXD2_QGPO Transmit data: serial output from the SCI2
