msCAN08 Controller (msCAN08)
BOFFIF — Bus-Off Interrupt Flag
This bit will be set when the msCAN08 went into bus-off status, due
to the Transmit Error counter exceeded 255. If not masked, an Error
interrupt is pending while this flag is set.
1 = msCAN08 went into bus-off status.
0 = No bus-off status has been reached.
OVRIF — Overrun Interrupt Flag
This bit will be set when a data overrun condition occurred. If not
masked, an Error interrupt is pending while this flag is set.
1 = A data overrun has been detected.
0 = No data overrun has occurred.
RXF — Receive Buffer Full
The RXF flag is set by the msCAN08 when a new message is
available in the foreground receive buffer. This flag indicates whether
the buffer is loaded with a correctly received message. After the CPU
has read that message from the receive buffer the RXF flag must be
handshaken to release the buffer. A set RXF flag prohibits the
exchange of the background receive buffer into the foreground buffer.
In that case the msCAN08 will signal an overload condition. If not
masked, a Receive interrupt is pending while this flag is set.
1 = The receive buffer is full. A new message is available.
0 = The receive buffer is released (not full).
NOTE: The CRFLG register is held in the reset state when the SFTRES bit in
CMCR0 is set.
