msCAN08 Controller (msCAN08)
Protocol violation protection
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 can not 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 msCAN08 module
control register (CMCR1) on page 379) serves as a lock to protect
the following registers:
â msCAN08 Module Control Register 1 (CMCR1)
â msCAN08 Bus Timing Register 0 and 1 (CBTR0, CBTR1)
â msCAN08 Identifier Acceptance Control Register (CIDAC)
â msCAN08 Identifier Acceptance Registers (CIDAR0-3)
â msCAN08 Identifier Mask Registers (CIDMR0-3)
⢠The TxCAN pin is forced to Recessive if the CPU goes into STOP
mode.
