Technical Data

NOTE:
Interrupts are directly associated with one or more status flags in either
the msCAN12 receiver flag register (CRFLG) or the msCAN12
transmitter flag register (CTFLG). Interrupts are pending as long as one
of the corresponding flags is set. The flags in above registers must be
reset within the interrupt handler in order to handshake the interrupt. The
flags are reset through writing a 1 to the corresponding bit position. A flag
can not be cleared if the respective condition still prevails.
Bit manipulation instructions (BSET) shall not be used to clear interrupt
flags.
The msCAN12 supports four interrupt vectors as shown in
The vector addresses and the relative interrupt priority are dependent on
the chip integration and to be defined.
