10.9.8.3 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)
Note: To modify the FFAx and FSCx bits, the be-
CAN must be in INIT mode.
Bit 7 = Reserved. Forced to 0 by hardware.
Bits 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 = Reserved. Forced to 0 by hardware.
Bits 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)
Bit 7 = Reserved. Forced to 0 by hardware.
Bits 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 = Reserved. Forced to 0 by hardware.
Bits 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
