Description
7
GATE1
1: Enables external gate control (pin INT1 for
Counter 1). When INT1 is high, and TRx bit is
set (see TCON register), a counter is
incremented every falling edge on the T1IN
input pin
6
C/T1
Selects timer or counter operation (Timer 1).
1 = A counter operation is performed
0 = The corresponding register will function
as a timer

T1M1
4
T1M0
3
GATE0
If set, enables external gate control (pin INT0
for Counter 0). When INT0 is high, and TRx
bit is set (see TCON register), a counter is
incremented every falling edge on the T0IN
input pin
2
C/T0
Selects timer or counter operation (Timer 0).
1 = A counter operation is performed
0 = The corresponding register will function
as a timer
1
T0M1
0
T0M0
The table below summarizes the four operating modes
of timers 0 and 1. The timer operating mode is
selected by the T1M1/T1M0 and T0M1/T0M0 bits of
the TMOD register.

Function
13-bit Counter
16-bit Counter
8-bit auto-reload Counter/Timer. The reload
value is kept in TH0 or TH1, while TL0 or TL1
is incremented every machine cycle. When TLx
overflows, the value of THx is copied to TLx.
If Timer 1 M1 and M0 bits are set to 1, Timer 1
stops.
