beCAN CONTROLLER (Cont’d)
CAN FILTER CONFIGURATION REG.1 (CFCR2)
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 = FSC5[1:0] Filter Scale Configuration
These bits define the scale configuration of Filter
5.
Bit 4 = FACT5 Filter Active
The software sets this bit to activate filter 5. To
modify the Filter 5 registers (CF5R[0:7]) the
FACT5 bit must be cleared.
0: Filter 5 is not active
1: Filter 5 is active
Bit 3 = Reserved. Forced to 0 by hardware.
Bits 2:1 = FSC4[1:0] Filter Scale Configuration
These bits define the scale configuration of Filter
4.
Bit 0 = FACT4 Filter Active
The software sets this bit to activate Filter 4. To
modify the Filter 4 registers (CF4R[0:7]), the
FACT4 bit must be cleared.
0: Filter 4 is not active
1: Filter 4 is active
