SYNCH — Synchronized Status
This bit indicates whether the MSCAN08 is synchronized to the CAN
bus and as such can participate in the communication process.
1 = MSCAN08 synchronized to the CAN bus
0 = MSCAN08 not synchronized to the CAN bus
TLNKEN — Timer Enable
This flag is used to establish a link between the MSCAN08 and the
on-chip timer (see Timer Link on page 342).
1 = The MSCAN08 timer signal output is connected to the Timer
Interface Module B Channel 0.
0 = The port is connected to the timer input.
SLPAK — Sleep Mode Acknowledge
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 MSCAN08 Sleep Mode on page 339). If the MSCAN08 detects
bus activity while in Sleep mode, it clears the flag.
1 = Sleep – MSCAN08 in internal sleep mode
0 = Wakeup – MSCAN08 is not in Sleep mode
