Mode 0
Putting either Timer into Mode 0 makes it look like an 8048 Timer,
which is an 8-bit Counter with a divide-by-32 prescaler. Figure 24
shows Mode 0 operation.
In this mode, the Timer register is configured as a 13-bit register. As
the count rolls over from all 1s to all 0s, it sets the Timer interrupt
flag TFn. The count input is enabled to the Timer when TRn = 1 and
either GATE = 0 or INTn = 1. (Setting GATE = 1 allows the Timer to
be controlled by external input INTn, to facilitate pulse width
measurements). TRn is a control bit in the Special Function Register
TCON (Figure 23). The GATE bit is in the TMOD register.
The 13-bit register consists of all 8 bits of THn and the lower 5 bits
of TLn. The upper 3 bits of TLn are indeterminate and should be
ignored. Setting the run flag (TRn) does not clear the registers.
Mode 0 operation is the same for Timer 0 and Timer 1. See
Figure 24. There are two different GATE bits, one for Timer 1
(TMOD.7) and one for Timer 0 (TMOD.3).

TF1
Timer 1 overflow flag. Set by hardware on Timer/Counter overflow. Cleared by hardware when the
interrupt is processed, or by software.
TCON.6
TR1
Timer 1 Run control bit. Set/cleared by software to turn Timer/Counter 1 on/off.
TCON.5
TF0
Timer 0 overflow flag. Set by hardware on Timer/Counter overflow. Cleared by hardware when the
processor vectors to the interrupt routine, or by software.
TCON.4
TR0
Timer 0 Run control bit. Set/cleared by software to turn Timer/Counter 0 on/off.
TCON.3
IE1
Interrupt 1 Edge flag. Set by hardware when external interrupt 1 edge is detected. Cleared by
hardware when the interrupt is processed, or by software.
TCON.2
IT1
Interrupt 1 Type control bit. Set/cleared by software to specify falling edge/low level triggered
external interrupts.
TCON.1
IE0
Interrupt 0 Edge flag. Set by hardware when external interrupt 0 edge is detected. Cleared by
hardware when the interrupt is processed, or by software.
TCON.0
IT0
Interrupt 0 Type control bit. Set/cleared by software to specify falling edge/low level triggered
external interrupts.
