All bits of this register are read only; all are cleared by a read of the register.
This register must be read in the interrupt handling routine in order to enable further interrupts.
WIF — Wake-up interrupt flag
If the MCAN detects bus activity whilst it is asleep, it clears the SLEEP bit in the CCOM register;
the WIF bit will then be set. WIF is cleared by reading the MCAN interrupt register (CINT), or by
an external reset.
OIF — Overrun interrupt flag
When OIE is set then this bit will be set when a data overrun condition is detected. Like all the bits
in this register, OIF is cleared by reading the register, or when reset request is set.
EIF — Error interrupt flag
When EIE is set then this bit will be set by a change in the error or bus status bits in the MCAN
status register. Like all the bits in this register, EIF is cleared by reading the register, or by an
external reset.
TIF — Transmit interrupt flag
The TIF bit is set at the end of a transmission whenever both the TBA and TIE bits are set. Like all
the bits in this register, TIF is cleared by reading the register, or when reset request is set.
