L
FABT
TIV
If 8 bit microprocessor the Data (TMDR Register) is taken into account by the transmitter after writing bits
8 to 15 of this register.
Transmit Monitor Address Register (after reading)
When this register is read by the microprocessor, these different bits mean:
READ, MA0/2, G0 have same definition as already described for the write register cycle.

VI.24 - Transmit Monitor Data Register
M08/01 : First Monitor Byte to transmit. M08 bit is transmitted first.
M18/11 : Second Monitor Byte to transmit if NOB = 0 (bit of TMAR). M18 bit is transmitted first.

: Last byte
: FABT = 1, the current message is aborted by the transmitter.
: Timer interrupt is Validated
: When this bit is at “1”, IDLE (all 1’s) is transmitted during the channel validation.
: EXECUTED
: NUMBER OF BYTE which has been transmitted.
: Last byte, this bit is the L bit which has been written by the microprocessor.
: ABORT
: Time Out one millisecond
L = 1, the word (or the byte) located in the Transmit Monitor Data Register (TMDR) is the last.
L = 0, the word (or the byte) located in the Transmit Monitor Data Register (TMDR) is not the
last.
TIV = 1, Time Out alarm generates an interrupt when the timer has expired.
TIV = 0, Time Out alarm is masked.
When this status bit is at “1”, the command written previously by the microprocessor has been
executed and a new word can be stored in the Transmit Monitor Data Register (TMDR) by the
microprocessor.
When this bit is at “0”, the command written previously by the microprocessor has not yet been
executed.
NOBT = 1, the first byte is transmitting.
NOB T = 0, the second byte is transmitting, the first byte has been transmitted.
ABT=1, the remote receiver has aborted the current message.
TO = 1, the remote receiver has not acknowledged the byte which has been transmitted one
millisecond ago.
