TIMERS
Each ADE5166/ADE5169/ADE5566/ADE5569 has three 16-bit
timers/counters: Timer/Counter 0, Timer/Counter 1, and Timer/
Counter 2. The timer/counter hardware is included on chip to
relieve the processor core of overhead inherent in implementing
timer/counter functionality in software. Each timer/counter con-
sists of two 8-bit registers: THx and TLx (x = 0, 1, or 2). All three
timers can be configured to operate as timers or as event counters.
When functioning as a timer, the TLx SFR is incremented every
machine cycle. Thus, it can be thought of as counting machine
cycles. Because a machine cycle on a single cycle core consists of
one core clock period, the maximum count rate is the core clock
frequency.

Description
Timer 1 gating control. Set by software to enable Timer/Counter 1 only when the INT1 pin is high and the TR1
control bit (Address 0x88[6]) is set. Cleared by software to enable Timer 1 whenever the TR1 control bit is set.
Timer 1 timer or counter select bit. Set by software to select counter operation (input from the T1 pin).
Cleared by software to select the timer operation (input from the internal system clock).
Timer 1 mode select bits.

Timer 0 gating control. Set by software to enable Timer/Counter 0 only when the INT0 pin is high and the TR0
control bit (Address 0x88[4]) is set. Cleared by software to enable Timer 0 whenever the TR0 control bit is set.
Timer 0 timer or counter select bit. Set by software to the select counter operation (input from the T0 pin).

Result
TH1 (Address 0x8D) operates as an 8-bit timer/counter. TL1 (Address 0x8B) serves as a
5-bit prescaler.
16-bit timer/counter. TH1 and TL1 are cascaded; there is no prescaler.
8-bit autoreload timer/counter. TH1 holds a value to reload into TL1 each time TL1 overflows.
Timer/Counter 1 stopped.
Result
TH0 (Address 0x8C) operates as an 8-bit timer/counter. TL0 (Address 0x8A) serves as a
5-bit prescaler.
16-bit timer/counter. TH0 and TL0 are cascaded; there is no prescaler.
8-bit autoreload timer/counter. TH0 holds a value to reload into TL0 each time TL0 overflows.
TL0 is an 8-bit timer/counter controlled by the standard Timer 0 control bits. TH0 is an
8-bit timer only, controlled by the Timer 1 control bits.

Timer/Counter 0 and Timer/Counter 1 control (see Table 114).
Timer/Counter 0 and Timer/Counter 1 mode (see Table 113).
Timer 0 low byte (see Table 117).
Timer 1 low byte (see Table 119).
Timer 0 high byte (see Table 116).
Timer 1 high byte (see Table 118).
Timer/Counter 2 control (see Table 115).
Timer 2 reload/capture low byte (see Table 123).
Timer 2 reload/capture high byte (see Table 122).
Timer 2 low byte (see Table 121).
Timer 2 high byte (see Table 120).
When functioning as a counter, the TLx SFR is incremented by
a 1-to-0 transition at its corresponding external input pin: T0,
T1, or T2. When the samples show a high in one cycle and a low
in the next cycle, the count is incremented. Because it takes two
machine cycles (two core clock periods) to recognize a 1-to-0
transition, the maximum count rate is half the core clock frequency.
There are no restrictions on the duty cycle of the external input
signal, but to ensure that a given level is sampled at least once
before it changes, it must be held for a minimum of one full
machine cycle. User configuration and control of all timer
operating modes is achieved via the SFRs listed in Table 112.
