timer mode is set, the overflow outputs of timer 0 and timer 2 are used as the input clock.
When any mode other than 16-bit timer mode is set, the input clock is selected from among
the internal clocks φT1, φT16, and φT256 as well as the comparator outputs (Match
detection signal) of timer 0 and timer 2 according to the set value of the T10MOD and te

Resetting sets <PRCK1:0> to 00, which selects the f
The 8-bit timers 0 and 1 select among 4 clock inputs: φT1, φT4, φT16, and φT256 of the
This prescaler can be run or stopped by the timer control register TRUN<PRRUN>.
Resetting clears <PRRUN> to 0 and stops the prescaler.
When the Idle1 mode (in which only the oscillator operates) is used, set TRUN<PRRUN>
This is an 8-bit binary counter which counts up by the input clock pulse specified by
The input clocks of timer 0 and timer 2 are selected from among the external clock from
The input clocks used by timer 1 and timer 3 depend on the operation mode. When 16-bit
Similarly, operation mode is also set by the T10MOD and the T32MOD registers. When
The counting and stop and clear of the up counter can be controlled for each interval
When T10MOD<T10M1:0> = 01, the overflow output of timer 0 becomes the input clock of timer 1
(16-bit timer mode).
When T10MOD<T10M1:0> = 00 and T10MOD<T1CLK1:0> = 01, φT1 becomes the input of timer 1
(8-bit timer mode).
