The programmer’s model has been laid out for maximum simplicity and
efficiency.
CSWAI — CAN Stops in Wait Mode
SYNCH — Synchronized Status
TLNKEN — Timer Enable
SLPAK — SLEEP Mode Acknowledge
This bit indicates whether the msCAN12 is synchronized to the CAN
bus and as such can participate in the communication process.
This flag is used to establish a link between the msCAN12 and the on-
chip timer (see
This flag indicates whether the msCAN12 is in module internal
SLEEP Mode. It shall be used as a handshake for the SLEEP Mode
request (see

For More Information On This Product,
0 = The module is not affected during WAIT mode.
1 = The module ceases to be clocked during WAIT mode.
0 = msCAN12 is not synchronized to the CAN bus
1 = msCAN12 is synchronized to the CAN bus
0 = The port is connected to the timer input.
1 = The msCAN12 timer signal output is connected to the timer
0 = Wake-up – The msCAN12 is not in SLEEP Mode.
1 = SLEEP – The msCAN12 is in SLEEP Mode.
