Table XV. TMOD SFR Bit Designations
Bit
Name
Description
7
Gate
Timer 1 Gating Control.
Set by software to enable Timer/Counter 1 only while
INT1 pin is high and TR1 control bit is set.
Cleared by software to enable Timer 1 whenever TR1 control bit is set.
6
C/T
Timer 1 Timer or Counter Select Bit.
Set by software to select counter operation (input from T1 pin).
Cleared by software to select timer operation (input from internal system clock).
5
M1
Timer 1 Mode Select Bit 1 (used with M0 Bit).
4
M0
Timer 1 Mode Select Bit 0.
M1
M0
0
TH1 operates as an 8-bit timer/counter. TL1 serves as 5-bit prescaler.
0
1
16-Bit Timer/Counter. TH1 and TL1 are cascaded; there is no prescaler.
1
0
8-Bit Autoreload Timer/Counter. TH1 holds a value that is to be
reloaded into TL1 each time it overflows.
1
Timer/Counter 1 Stopped.
3
Gate
Timer 0 Gating Control.
Set by software to enable Timer/Counter 0 only while
INT0 pin is high and TR0 control bit is set.
Cleared by software to enable Timer 0 whenever TR0 control bit is set.
2
C/T
Timer 0 Timer or Counter Select Bit.
Set by software to select counter operation (input from T0 pin).
Cleared by software to select timer operation (input from internal system clock).

1
16-Bit Timer/Counter. TH0 and TL0 are cascaded; there is no prescaler.
1
0
8-Bit Autoreload Timer/Counter. TH0 holds a value that is to be
reloaded into TL0 each time it overflows.
1
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.
User configuration and control of all Timer operating modes is achieved via three SFRs:
TMOD, TCON
Control and configuration for Timers 0 and 1.
T2CON
Control and configuration for Timer 2.
Timer/Counter 0 and
TMOD
1 Mode Register
