Special Function Register TMOD (Address 89H)
Reset Value : 00H
Bit
Function
GATE
Gating control
When set, timer/counter “x” is enabled only while “INT x” pin is high and “TRx”
control bit is set.
When cleared timer “x” is enabled whenever “TRx” control bit is set.
C/T
Counter or timer select bit
Set for counter operation (input from “Tx” input pin).
Cleared for timer operation (input from internal system clock).

8-bit timer/counter:
“THx” operates as 8-bit timer/counter
“TLx” serves as 5-bit prescaler
0
1
16-bit timer/counter.
“THx” and “TLx” are cascaded; there is no prescaler
1
0
8-bit auto-reload timer/counter.
“THx” holds a value which is to be reloaded into “TLx” each
time it overflows

Timer 0 :
TL0 is an 8-bit timer/counter controlled by the standard
timer 0 control bits. TH0 is an 8-bit timer only controlled by
timer 1 control bits.
Timer 1 :
Timer/counter 1 stops
