10.10.8.3 CAN Filter Registers

CAN FILTER CONFIGURATION REG.0 (CFCR0)

All bits of this register are set and cleared by soft-

ware.

Read / Write

Reset Value: 0000 0000 (00h)

7

0

FFA1 FSC11 FSC10 FACT1 FFA0 FSC01 FSC00 FACT0

Note: To modify the FFAx and FSCx bits, the bx-

CAN must be in INIT mode.

Bit 7 = FFA1 Filter FIFO Assignment for Filter 1

The message passing through this filter will be

stored in the specified FIFO.

0: Filter assigned to FIFO 0

1: Filter assigned to FIFO 1

Bit 6:5 = FSC1[1:0] Filter Scale Configuration

These bits define the scale configuration of Filter

1.

Bit 4 = FACT1 Filter Active

The software sets this bit to activate Filter 1. To

modify the Filter 1 registers (CF1R[7:0]), the

FACT1 bit must be cleared.

0: Filter 1 is not active

1: Filter 1 is active

Bit 3 = FFA0 Filter FIFO Assignment for Filter 0

The message passing through this filter will be

stored in the specified FIFO.

0: Filter assigned to FIFO 0

1: Filter assigned to FIFO 1

Bit 2:1 = FSC0[1:0] Filter Scale Configuration

These bits define the scale configuration of Filter

0.

Bit 0 = FACT0 Filter Active

The software sets this bit to activate Filter 0. To

modify the Filter 0 registers (CF0R[0:7]), the

FACT0 bit must be cleared.

0: Filter 0 is not active

1: Filter 0 is active

CAN FILTER CONFIGURATION REG.1 (CFCR1)

All bits of this register are set and cleared by soft-

ware.

Read / Write

Reset Value: 0000 0000 (00h)

FFA3 FSC31 FSC30 FACT3 FFA2 FSC21 FSC20 FACT2

Bit 7 = FFA3 Filter FIFO Assignment for Filter 3

The message passing through this filter will be

stored in the specified FIFO.

0: Filter assigned to FIFO 0

1: Filter assigned to FIFO 1

Bit 6:5 = FSC3[1:0] Filter Scale Configuration

These bits define the scale configuration of Filter

3.

Bit 4 = FACT3 Filter Active

The software sets this bit to activate filter 3. To

modify the Filter 3 registers (CF3R[0:7]) the

FACT3 bit must be cleared.

0: Filter 3 is not active

1: Filter 3 is active

Bit 3 = FFA2 Filter FIFO Assignment for Filter 2

The message passing through this filter will be

stored in the specified FIFO.

0: Filter assigned to FIFO 0

1: Filter assigned to FIFO 1

Bit 2:1 = FSC2[1:0] Filter Scale Configuration

These bits define the scale configuration of Filter

2.

Bit 0 = FACT2 Filter Active

The software sets this bit to activate Filter 2. To

modify the Filter 2 registers (CF2R[0:7]), the

FACT2 bit must be cleared.

0: Filter 2 is not active

1: Filter 2 is active
