bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
bit 7 SOF: Start-of-Frame signal bit
If CANCTRL.CLKEN = 1:
1 = CLKOUT pin enabled for SOF signal
0 = CLKOUT pin enabled for clockout function
If CANCTRL.CLKEN = 0, Bit is don’t care.
bit 6 WAKFIL: Wake-up Filter bit
1 = Wake-up filter enabled
0 = Wake-up filter disabled
bit 5-3 Unimplemented: Reads as ‘0’
bit 2-0 PHSEG2: PS2 Length bits<2:0>
(PHSEG2 + 1) x T
Q
Minimum valid setting for PS2 is 2 TQ
