Resets and Interrupts
14.3.2.11 Timebase Module (TBM)
The timebase module can interrupt the CPU on a regular basis with a rate defined by TBR2–TBR0. When
the timebase counter chain rolls over, the TBIF flag is set. If the TBIE bit is set, enabling the timebase
interrupt, the counter chain overflow will generate a CPU interrupt request.
Interrupts must be acknowledged by writing a logic 1 to the TACK bit.
14.3.2.12 MSCAN
MSCAN08 interrupt sources:

MSCAN08 transmitter empty bits (TXE0–TXE2) — The TXEx bit is set when the corresponding
MSCAN08 data buffer is empty. The MSCAN08 transmit interrupt enable bits, TXEIE0–TXEIE2,
enables transmitter CPU interrupt requests. TXEx is in MSCAN08 transmitter flag register. TXEIEx
is in MSCAN08 transmitter control register.
MSCAN08 receiver full bit (RXF) — The RXF bit is set when the a MSCAN08 message has been
successfully received and loaded into the foreground receive buffer. The MSCAN08 receive
interrupt enable bit, RXFIE, enables receiver CPU interrupt requests. RXF is in MSCAN08 receiver
flag register. RXFIE is in MSCAN08 receiver interrupt enable register.
MSCAN08 wakeup bit (WUPIF) — WUPIF is set when activity on the CAN bus occurred during the
MSCAN08 internal sleep mode. The wakeup interrupt enable bit, WUPIE, enables MSCAN08
wakeup CPU interrupt requests. WUPIF is in MSCAN08 receiver flag register. WUPIE is in
MSCAN08 receiver interrupt enable register.
Overrun bit (OVRIF) — OVRIF is set when both the foreground and the background receive
message buffers are filled with correctly received messages and a further message is being
received from the bus. The overrun interrupt enable bit, OVRIE, enables OVRIF to generate
MSCAN08 error CPU interrupt requests. OVRIF is in MSCAN08 receiver flag register. OVRIE is in
MSCAN08 receiver interrupt enable register.
Receiver Warning bit (RWRNIF) — RWRNIF is set when the receive error counter has reached the
CPU warning limit of 96. The receiver warning interrupt enable bit, RWRNIE, enables RWRNIF to
generate MSCAN08 error CPU interrupt requests. RWRNIF is in MSCAN08 receiver flag register.
RWRNIE is in MSCAN08 receiver interrupt enable register.
Transmitter Warning bit (TWRNIF) — TWRNIF is set when the transmit error counter has reached
the CPU warning limit of 96. The transmitter warning interrupt enable bit, TWRNIF, enables
TWRNIF to generate MSCAN08 error CPU interrupt requests. TWRNIF is in MSCAN08 receiver
flag register. TWRNIE is in MSCAN08 receiver interrupt enable register.
Receiver Error Passive bit (RERRIF) — RERRIF is set when the receive error counter has
exceeded the error passive limit of 127 and the MSCAN08 has gone to error passive state. The
receiver error passive interrupt enable bit, RERRIE, enables RERRIF to generate MSCAN08 error
CPU interrupt requests. RERRIF is in MSCAN08 receiver flag register. RERRIE is in MSCAN08
receiver interrupt enable register.
Transmitter Error Passive bit (TERRIF) — TERRIF is set when the transmit error counter has
exceeded the error passive limit of 127 and the MSCAN08 has gone to error passive state. The
transmit error passive interrupt enable bit, TERRIE, enables TERRIF to generate MSCAN08 error
CPU interrupt requests. TERRIF is in MSCAN08 receiver flag register. TERRIE is in MSCAN08
receiver interrupt enable register.
