1 Product Description

The TPMC310 is a conduction cooled single-width 32 bit PMC module providing a two channel high speed CAN bus interface.

The PLX Technology PCI9030 PCI Target Chip is used for the PCI bus interface. Two Philips SJA1000 CAN Controllers (CAN specification 2.0B supported) are used for the CAN bus

interface (one for each channel). The CAN bus I/O interface provides two independent channels, isolated from system logic and from

each other. CAN High Speed transceivers are used for the CAN bus I/O interface. An on board termination option (solder pads) is provided for each CAN bus channel allowing to

configure on board termination and/or pass trough mode for the CAN bus. The TPMC310 uses the P14 I/O connector for the CAN bus I/O interface.

After power-up or board reset the CAN controllers are set to reset mode. To set the CAN controllers to operating mode, the CANx_RST# bit must be set to ‘1’.

After power-up or board reset the CAN bus transceivers are set to silent mode. To set the CAN bus transceivers to operating mode, the CANx_SEL bit must be set to ‘1’.

Disabling interrupts in the CAN Control Register only affects the interrupt mapping to the PCI9030 LINTx# local interrupt inputs. It will not affect the interrupt source of the SJA1000 CAN controllers.

If enabled, the CAN CH1 interrupt source is mapped to the PCI9030 LINT1# local interrupt input. If enabled, the CAN CH2 interrupt source is mapped to the PCI9030 LINT2# local interrupt input. The PCI9030 LINTx# local interrupt inputs are used in active low level sensitive mode.

The CAN interrupts must be acknowledged via SJA1000 registers (CAN Controller Register Space). Please see the SJA1000 CAN Controller Manual for more information.

4.1.2 PCI Base Address Initialization

PCI Base Address Initialization is scope of the PCI host software.

PCI9030 PCI Base Address Initialization:

1. Write 0xFFFF_FFFF to the PCI9030 PCI Base Address Register

2. Read back the PCI9030 PCI Base Address Register

3. For PCI Base Address Registers 0:5, check bit 0 for PCI Address Space: Bit 0 = '0' requires PCI Memory Space mapping Bit 0 = '1' requires PCI I/O Space mapping For the PCI Expansion ROM Base Address Register, check bit 0 for usage: Bit 0 = ‘0’: Expansion ROM not used Bit 0 = ‘1’: Expansion ROM used

4. For PCI I/O Space mapping, starting at bit location 2, the first bit set determines the size of the required PCI I/O Space size.

For PCI Memory Space mapping, starting at bit location 4, the first bit set to '1' determines the size of the required PCI Memory Space size.

For PCI Expansion ROM mapping, starting at bit location 11, the first bit set to '1' determines the required PCI Expansion ROM size.

For example, if bit 5 of a PCI Base Address Register is detected as the first bit set to ‘1’, the PCI9030 is requesting a 32 byte space (address bits 4:0 are not part of base address decoding).

5. Determine the base address and write the base address to the PCI9030 PCI Base Address Register. For PCI Memory Space mapping the mapped address region must comply with the definition of bits 3:1 of the PCI9030 PCI Base Address Register.

After programming the PCI9030 PCI Base Address Registers, the host software must enable the PCI9030 for PCI I/O and/or PCI Memory Space access in the PCI9030 PCI Command Register (Offset 0x04):

To enable PCI I/O Space access to the PCI9030, bit 0 must be set to '1'. To enable PCI Memory Space access to the PCI9030, bit 1 must be set to '1'.

4.4 Local Software Reset

The PCI9030 Local Reset Output LRESETo# is used to reset the on board local logic. The PCI9030 local reset is active during PCI reset or if the PCI Adapter Software Reset bit is set in the

PCI9030 local configuration register CNTRL (offset 0x50).

CNTRL[30] PCI Adapter Software Reset:

Value of 1 resets the PCI9030 and issues a reset to the Local Bus (LRESETo# asserted). The PCI9030 remains in this reset condition until the PCI Host clears this bit. The contents of the PCI9030 PCI and Local Configuration Registers are not reset. The PCI9030 PCI Interface is also not reset.

5 Programming Hints

5.1 CAN Controller (SJA1000)

Clock Source:

The SJA1000 clock input frequency is 16 MHz (for both SJA1000 CAN controllers).

Reset Mode:

After power-up or board reset the SJA1000 CAN controllers are held in “reset mode”. To bring the SJA1000 CAN controllers out of reset mode, the CANx_RST# bit(s) in the CAN Control

Silent Mode:

After power-up or board reset the CAN bus transceivers are held in “silent mode”. To bring the CAN bus transceivers to operating mode, the CANx_SEL bit(s) in the CAN Control

Output Control Register:

The SJA1000 Output Control Register must be programmed as follows (for both SJA1000 CAN controllers in the SJA1000 controller internal reset mode - see SJA1000 Control Register in the SJA1000 CAN Controller Manual):

6 Configuration Hints

6.1 I/O Line Configuration

The I/O line configuration is configured by on board solder pads (there is no jumper solution because the TPMC310 is considered to be used in a vibration-sensitive environment).

Possible line configuration options for each of the two I/O channels (CAN CH1, CAN CH2) are:

• On board Termination Mode : on / off

• Bus Mode : bus_end / pass_through

The on board termination option for a CAN I/O channel node input (see P14 I/O pin assignment) is a 120 ohm split termination network.

For the bus_end option, the I/O lines are NOT passed through from the node input pins to the node output pins of the P14 I/O connector. The node input pins must be used to connect the CAN bus lines (see P14 I/O pin assignment).

For the pass_through option, the I/O lines are passed through from the node input pins to the node output pins of the P14 I/O connector (see P14 I/O pin assignment).

Table 7-1 : P14 I/O Pin Assignment

Be sure that the P14 connector I/O signals used by the TPMC310 (including the reserved pins) are available and not otherwise used on the J14 connector of the PMC carrier board.

The "Out-Node" for each CAN channel is only available if the on board I/O line configuration is set accordingly (pass_through mode).
