0 No interrupt request is generated from this event.
1 A CAN Status Change event causes an error interrupt request.
Receiver Status Change Enable — These RSTAT enable bits control the sensitivity level in which receiver state
changes are causing CSCIF interrupts. Independent of the chosen sensitivity level the RSTAT flags continue to
indicate the actual receiver state and are only updated if no CSCIF interrupt is pending.
00 Do not generate any CSCIF interrupt caused by receiver state changes.
01 Generate CSCIF interrupt only if the receiver enters or leaves “bus-off” state. Discard other receiver state
10 Generate CSCIF interrupt only if the receiver enters or leaves “RxErr” or “bus-off”
11 Generate CSCIF interrupt on all state changes.
Transmitter Status Change Enable — These TSTAT enable bits control the sensitivity level in which transmitter
state changes are causing CSCIF interrupts. Independent of the chosen sensitivity level, the TSTAT flags
continue to indicate the actual transmitter state and are only updated if no CSCIF interrupt is pending.
00 Do not generate any CSCIF interrupt caused by transmitter state changes.
01 Generate CSCIF interrupt only if the transmitter enters or leaves “bus-off” state. Discard other transmitter

MSCAN Receiver Interrupt Enable Register (CANRIER)
WUPIE
The CANRIER register is held in the reset state when the initialization mode
is active (INITRQ=1 and INITAK=1). This register is writable when not in
initialization mode (INITRQ=0 and INITAK=0).
The RSTATE[1:0], TSTATE[1:0] bits are not affected by initialization
mode.
