The lowest value will give the highest priority. If two channels have the same priority,
one of them will never be able to send its interrupt vector to the microprocessor. Each
channel must have a unique channel priority order.

Function
Comments
Bit 15
Channel enable
0: channel is out of service
1: channel is in service
Bit 14
Test mode
0: external ARINC lines as input (normal operation)
1: third transmitter lines as input (test mode)
Bit 13
Label control
0: no control, all the labels are accepted
1: automatic check of the label according to the label control matrix
Bit 12
LCMWE label control matrix
write enable
0: receiving mode (write to the matrix are disabled)
1: programmation mode for labels control matrix
Bit 11
Parity control
0: even parity check
1: odd parity check
Bit 10
Parity control
0: parity check is disable
1: parity check is enable

Bit 7
Wrong parity: this feature is
enabled only if the self-test
register bit 0 is set 1
0: received message parity is correct if read, reset wrong wrong parity flag if written.
1: an incorrect received message parity has been detected (the corresponding
message is lost) (set by hardware).
