5.0 TIMERS/COUNTERS
5.1 Timers
The device has three 16-bit registers that can be used as
either timers or event counters. The three timers/counters
are denoted Timer 0 (T0), Timer 1 (T1), and Timer 2 (T2).
Each is designated a pair of 8-bit registers in the SFRs.
The pair consists of a most significant (high) byte and least
significant (low) byte. The respective registers are TL0,
TH0, TL1, TH1, TL2, and TH2.
5.2 Timer Set-up
Refer to Table 3-10 for TMOD, TCON, and T2CON regis-
ters regarding timers T0, T1, and T2. The following tables
provide TMOD values to be used to set up Timers T0, T1,
and T2.
Except for the baud rate generator mode, the values given
for T2CON do not include the setting of the TR2 bit. There-
fore, bit TR2 must be set separately to turn the timer on.

1. The Timer is turned ON/OFF by setting/clearing
bit TR0 in the software.
2. The Timer is turned ON/OFF by the 1 to 0 transition
on INT0# (P3.2) when TR0 = 1 (hardware control).
