MSCAN
TSTATE1, TSTATE0 — Transmitter Status Change Enable
These TSTAT enable bits control the sensitivity level in which
transmitter state changes are causing CSCIF interrupts. Independent
of the chosen sensitivity level the TSTAT flags still indicate the actual
transmitter state and are only updated if no CSCIF interrupt is
pending.
11 = generate CSCIF interrupt on all state changes
10 = generate CSCIF interrupt only if the transmitter enters or
leaves ‘TxErr’ or ‘BusOff’ state. Discard other transmitter state
changes for generating CSCIF interrupt.
01 = generate CSCIF interrupt only if the transmitter enters or
leaves ‘BusOff’ state. Discard other transmitter state changes
for generating CSCIF interrupt.
00 = do not generate any CSCIF interrupt caused by transmitter
state changes.
OVRIE — Overrun Interrupt Enable
1 = An overrun event causes an error interrupt request.
0 = No interrupt request is generated from this event.
RXFIE — Receiver Full Interrupt Enable
1 = A receive buffer full (successful message reception) event
causes a receiver interrupt request.
0 = No interrupt request is generated from this event.
