LAST

BYTE

INIT

IR/W = 0

Writing auxiliary memory.

CR5/CR3

not used

LAST

Last Byte.

This bit is associated with BYTE.

If LAST = 1, last byte of the message.

If LAST = 0, current byte

BYTE

Byte to transmit.

INIT

When this bit is at 1, the MON channel defined in SRC Register is initialised and the

Monitor Channel is idle (All ”1”s are transmitted)

ABT

LAST

BYTE

IDLE

R/W = 1

Read auxiliary memory

After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the bits of the

Time Out = one millisecond.

This bit goes to 1 when the remote receiver has not acknowledged the byte after 1

millisecond.

ABT

Abort.

ABT = 1 The remote receiver has aborted the message transmitting.

LAST

Last Byte.

This bit is associated with BYTE.

If LAST = 1, last byte of the message.

If LAST = 0, current byte.

BYTE

BYTE = 1 Byte transmitting.

BYTE = 0 Byte transmitted and acknowledged by the Remote

Receiver, a new byte can be transmitted.

IDLE

IDLE = 1

Monitor channel, A bit, E bit are at ”1”.

EOM

R/W = 1

Read auxiliary memory

After writing this register with R/W=1 and when BUSY(status register) has gone to 0, the bits of the

Abort.

AB = 1 The receiver has detected an error during the transmission.
