TIMER/COUNTER 0 AND 1 OPERATING MODES
The following paragraphs describe the operating modes for
Timer/Counters 0 and 1. Unless otherwise noted, it should be
assumed that these modes of operation are the same for Timer 0
as for Timer 1.
Mode 0 (13-Bit Timer/Counter)
Mode 0 configures an 8-bit Timer/Counter with a divide-by-32
prescaler. Figure 45 shows mode 0 operation.

Figure 45. Timer/Counter 0, Mode 0
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 over-
flow flag TF0. The overflow flag, TF0, can then be used to request
an interrupt. The counted input is enabled to the timer when
TR0 = 1 and either Gate = 0 or
INT0 = 1. Setting Gate = 1
allows the timer to be controlled by external input
INT0, to
facilitate pulsewidth measurements. TR0 is a control bit in the
special function register TCON; Gate is in TMOD. The 13-bit
register consists of all eight bits of TH0 and the lower five bits of
TL0. The upper three bits of TL0 are indeterminate and should
be ignored. Setting the run flag (TR0) does not clear the registers.
Mode 1 (16-Bit Timer/Counter)
Mode 1 is the same as Mode 0, except that the timer register is
running with all 16 bits. Mode 1 is shown in Figure 46.

Mode 2 (8-Bit Timer/Counter with Autoreload)
Mode 2 configures the timer register as an 8-bit counter (TL0)
with automatic reload, as shown in Figure 47. Overflow from
TL0 not only sets TF0, but also reloads TL0 with the contents
of TH0, which is preset by software. The reload leaves TH0
unchanged.

Mode 3 (Two 8-Bit Timer/Counters)
Mode 3 has different effects on Timer 0 and Timer 1. Timer 1 in
Mode 3 simply holds its count. The effect is the same as setting
TR1 = 0. Timer 0 in Mode 3 establishes TL0 and TH0 as two
separate counters. This configuration is shown in Figure 50.
TL0 uses the Timer 0 control bits: C/T, Gate, TR0,
INT0, and
TF0. TH0 is locked into a timer function (counting machine
cycles) and takes over the use of TR1 and TF1 from Timer 1.
Thus, TH0 now controls the Timer 1 interrupt. Mode 3 is
provided for applications requiring an extra 8-bit timer or counter.
When Timer 0 is in Mode 3, Timer 1 can be turned on and off
by switching it out of, and into, its own Mode 3, or can still be
used by the serial interface as a baud rate generator. In fact, it can
be used in any application not requiring an interrupt from
Timer 1 itself.
