Description
Reset Interrupt Flag
Status flag indicating that the HCAN module has
been reset. This bit cannot be masked by the
interrupt mask register (IMR). If this bit is not
cleared to 0 after entering power-on reset or
returning from software standby mode, interrupt
processing will start immediately when the
interrupt controller enables interrupts.
[Setting condition]
[Clearing condition]
Reserved
These bits are always read as 0. The write value
should always be 0.
Bus Operation Interrupt Flag
Status flag indicating detection of a dominant bit
due to bus operation when the HCAN module is in
HCAN sleep mode.
[Setting condition]
[Clearing condition]
Reserved
These bits are always read as 0. The write value
should always be 0.
