TIMER 0 AND TIMER 1
Timer 0 High/Low and Timer 1 High/Low Data SFRs
Each timer consists of two 8-bit SFRs. They are Timer 0 high
byte (TH0, Address 0x8C), Timer 0 low byte (TL0, Address 0x8A),
Timer 1 high byte (TH1, Address 0x8D), and Timer 1 low byte
(TL1, Address 0x8B). These SFRs can be used as independent
registers or combined into a single 16-bit register, depending on
the timer mode configuration (see Table 116 to Table 119).
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 97 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 (Address 0x88[5]). TF0 can then be used to
request an interrupt. The counted input is enabled to the timer
when TR0 = 1 and either Gate0 to 0 or INT0 = 1. Setting Gate0
to 1 allows the timer to be controlled by the 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, Address 0x88); the Gate0/Gate1 bits are in
Timer/Counter 0 and Timer/Counter 1 mode SFR (TMOD,
Address 0x89). The 13-bit register consists of all eight bits of
Timer 0 high byte SFR (TH0, Address 0x8C) and the lower five
bits of Timer 0 low byte SFR (TL0, Address 0x8A). The upper
three bits of TL0 SFR 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 98.
