This bit indicates whether the MSCAN08 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 MSCAN08 and the on-chip timer (see
This flag indicates whether the MSCAN08 is in module internal sleep mode. It shall be used as a
handshake for the sleep mode request (see
bus activity while in sleep mode, it clears the flag.
This flag requests the MSCAN08 to go into an internal power-saving mode (see

1 = MSCAN08 synchronized to the CAN bus
0 = MSCAN08 not synchronized to the CAN bus
1 = The MSCAN08 timer signal output is connected to the timer input.
0 = The port is connected to the timer input.
1 = Sleep – MSCAN08 in internal sleep mode
0 = Wakeup – MSCAN08 is not in sleep mode
1 = Sleep — The MSCAN08 will go into internal sleep mode.
0 = Wakeup — The MSCAN08 will function normally.
