TIMER 0 AND TIMER 1
Timer/Counter 0 and Timer/Counter 1 Data Registers
Each timer consists of two 8-bit registers. They are Timer 0
High Byte SFR (TH0, 0x8C), Timer 0 Low Byte SFR (TL0,
0x8A), Timer 1 High Byte SFR (TH1, 0x8D) and Timer 1 Low
Byte SFR (TL1, 0x8B) These can be used as independent
registers or combined into a single 16-bit register, depending on
the timer mode configuration (see Table 102 to Table 105).

Timer/Counter 0 and Timer/Counter 1 Operating Modes
This section describes the operating modes for Timer/Counter 0
and Timer/Counter 1. Unless otherwise noted, these modes of
operation are the same for both Timer 0 and Timer 1.
Mode 0 (13-Bit Timer/Counter)
Mode 0 configures an 8-bit timer/counter. Figure 82 shows
Mode 0 operation. Note that the divide-by-12 prescaler is not
present on the single-cycle core.
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
overflow flag, TF0. 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 Gate0 = 1 allows the timer to be
controlled by external input INT0 to facilitate pulse-width
measurements. TR0 is a control bit in the Timer/Counter 0 and
Timer/Counter 1 Control SFR (TCON, 0x88); the Gate bit is in
Timer/Counter 0 and Timer/Counter 1 Mode SFR (TMOD,
0x89). The 13-bit register consists of all 8 bits of Timer 0 High
Byte SFR (TH0, 0x8C) and the lower 5 bits of Timer 0 Low Byte
SFR (TL0, 0x8A). The upper 3 bits of Timer 0 Low Byte SFR
(TL0, 0x8A) 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 Mode 1 timer
register runs with all 16 bits. Mode 1 is shown in Figure 83.
