GATE When TRx (in TCON) is set and GATE=1, TIMER/
COUNTERx will run only while INTx pin is high
(hardware control). When GATE=0, TIMER/
COUNTERx will run only while TRx=1 (software
control).
C/

Timer or Counter selector. Cleared for Timer
operation (input from internal system clock). Set
for Counter operation (input from Tx input pin).

Enable the multiprocessor com-
munication feature in mode 2 and 3. In
mode 2 or 3, if SM2 is set to 1 then RI
will not be activated if the received 9th
data bit (RB8) is 0. In mode 1, if
SM2=1 then RI will not be activated if
valid stop bit was not received. In
mode 0, SM2 should be 0.
Set/Cleared by software to Enable/
Disable reception.
The 9th bit that will be transmitted in
mode 2 and 3. Set/Cleared by
software.
In modes 2 and 3, RB8 is the 9th data
bit that was received. In mode 1, if
SM2=0, RB8 is the stop bit that was
received. In mode 0, RB8 is not used.
Transmit interrupt flag. Set by
hardware at the end of the 8th bit time
in mode 0, or at the beginning of the
stop bit in the other modes. Must be
cleared by software.
Receive interrupt flag. Set by hardware
at the end of the 8th bit time in mode
0, or halfway through the stop bit time
in the other modes (except see SM2).
Must be cleared by software.
