SECOND CASE CM = 0: ACCESS TO AUXILIARY MEMORY
Microprocessor writes Auxiliary Memory to transmit Primitives for each TX C/I channel and to transmit
Bytes of message for each TX MON channel.
Microprocessor reads Auxiliary memory to recover Primitive received by each RX C/I channel and to re-
cover the message received by each RX MON channel.
TX Command Indicate channel - Selected by Destination Register (DST)

After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the
bits of the register have the following meaning:
Not used
Primitive trasmitted
PT0
Status
0
Primitive has not been transmitted yet
1
Primitive has been transmitted once
0
Primitive has been transmitted twice
1
Primitive has been transmitted more than twice.

Read auxiliary memory
After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the bits of the
register have the following meaning:
CR5/CR2
Not used
OVR
Overrun
OVR = 1. The previous primitive has not been read by the microprocessor.
PR
Primitive Received.
PR = 1. The primitive has been received once
PR = 0. The primitive has been received twice or more.
The primitive is in Source Register.
R/W = 0
Writing auxiliary memory.
