msCAN08 Controller (msCAN08)
Programmer’s model of control registers
WUPIF — Wake-up interrupt flag
If the msCAN08 detects bus activity whilst it is asleep, it clears the
SLPAK bit in the CMCR0 register; the WUPIF bit will then be set. If
not masked, a Wake-Up interrupt is pending while this flag is set.
1 = msCAN08 has detected activity on the bus and requested
wake-up.
0 = No wake-up activity has been observed while in sleep mode.
RWRNIF — Receiver warning interrupt flag
This bit will be set when the msCAN08 went into warning status due
to the Receive Error counter being in the range of 96 to 127. If not
masked, an Error interrupt is pending while this flag is set.
1 = msCAN08 went into receiver warning status.
0 = No receiver warning status has been reached.
TWRNIF — Transmitter warning interrupt flag
This bit will be set when the msCAN08 went into warning status due
to the Transmit Error counter being in the range of 96 to 127. If not
masked, an Error interrupt is pending while this flag is set.
1 = msCAN08 went into transmitter warning status.
0 = No transmitter warning status has been reached.
RERRIF — Receiver error Passive Interrupt Flag
This bit will be set when the msCAN08 went into error passive status
due to the Receive Error counter exceeded 127. If not masked, an
Error interrupt is pending while this flag is set.
1 = msCAN08 went into receiver error passive status.
0 = No receiver error passive status has been reached.
TERRIF — Transmitter Error Passive Interrupt Flag
This bit will be set when the msCAN08 went into error passive status
due to the Transmit Error counter exceeded 127. If not masked, an
Error interrupt is pending while this flag is set.
1 = msCAN08 went into transmitter error passive status.
0 = No transmitter error passive status has been reached.
