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.

Table 3-3 : CAN Control Register

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.

Table 3-4 : CAN Status Register

The CAN CHx controller interrupt request status is '0' for "no active interrupt request" and '1'

for "active interrupt request".

Please see the SJA1000 CAN Controller Manual for more information.

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.
