MASK REGISTER (MASK)

MLSYNC

MPDIF

MPRS

MMONR

MMONT

MCIR

MEXT

MINS

After Reset FF (H)

Each interrupt of Interrupt Register can be masked by the mask bit associated if this last is at ”1”.

RECEIVE MONITOR STATUS REGISTER (RMOS)

EVENT

BYTE

EOM

After Reset 00 (H)

After Reading, Event bit goes to ”0”.

EVENT

EVENT.

EVENT = 1. An event is occurred concerning the RX Monitor Channel identified by

M0, G2, G1, G0.

EVENT = 0. No event occurred concerning the RX Monitor Channels.

BYTE

A new byte is available in Auxiliary Memory. The microprocessor can read this byte

EOM

End of message.

The previous byte which has been taken into account by the microprocessor was the

last of the message.

ABORT.

ABORT = 1. The message received has been aborted by the transmitter.

GCI Multiplex 0 if MO = 0

GCI Multiplex 1 if MO = 1.

G 0/2

GCI channel 0 to 7 for each multiplex.

TRANSMIT MONITOR STATUS REGISTER (TMOS)

EVENT

BACK

ABT

After Reset 00 (H)

EVENT

EVENT = 1.

An event is occurred concerning the TX Monitor Channel identified by

MO, G2, G1, G0.

EVENT = 0.

No event concerning the TX Monitor Channels.

BACK

Byte acknowledged.

BACK = 1. The current byte transmitted has been acknowledged by the remote

receiver.

NB : when EVENT = 1 and TO = 0 and ABT = 0 and BACK = 0, it means end of

message. A newmessage can be transmitted.

Time Out.

The remote receiver has not acknowledged the byte transmitted during 1millisecond

(the Timer is validated in accordance with TIMD of MultiplexConfiguration 2 Register).

ABT

ABORT.

The byte transmitting has been aborted.

GCI Multiplex 0 if MO = 0

GCI Multiplex 1 if MO = 1.

G 0/2

GCI channel 0 to 7 for each multiplex.
