21.7.2 Interrupt Vectors
21.8 Protocol Violation Protection
MC68HC08AZ60A — Rev 0.0
MOTOROLA
The MSCAN08 supports four interrupt vectors as shown in
The vector addresses and the relative interrupt priority are defined in
Table
The MSCAN08 will protect the user from accidentally violating the CAN
protocol through programming errors. The protection logic implements
the following features:
•
•
The receive and transmit error counters cannot be written or
otherwise manipulated.
All registers which control the configuration of the MSCAN08 can
not be modified while the MSCAN08 is on-line. The SFTRES bit in
the MSCAN08 module control register (see
Control Register 0
following registers:
– MSCAN08 module control register 1 (CMCR1)
– MSCAN08 bus timing register 0 and 1 (CBTR0 and CBTR1)
– MSCAN08 identifier acceptance control register (CIDAC)
– MSCAN08 identifier acceptance registers (CIDAR0–3)
