MCAN command
register (CCOM)
11-mcan
NOTE:
Reset: with RR bit set
External Reset:
Address:
RX0 — Receive pin 0 (passive) (Refer to
RX1 — Receive pin 1 (passive) (Refer to
If both RX0 and RX1 are set, or both are clear, then neither of the RX
pins will be disconnected.
COMPSEL — Comparator selector
This is a write only register; a read of this location will always return
the value $FF.
This register may be written only when the RR bit in CCNTRL is clear.
Do not use read-modify-write instructions on this register (e.g. BSET,
BCLR).

1 = VDD/2 will be connected to the input comparator. The RX0 pin
0 = The RX0 pin will be connected to the input comparator. VDD/2
1 = VDD/2 will be connected to the input comparator. The RX1 pin
0 = The RX1 pin will be connected to the input comparator. VDD/2
1 = RX0 and RX1 will be compared with VDD/2 during sleep mode
0 = RX0 will be compared with RX1 during sleep mode.
