11.5.1 8-bit
Timer/Event Counter 0, 1
11.5.1.1 Overview
Timer 0 and timer 1 can be used either two 8-bit timer/counter or one 16-bit timer/counter with
combine them. Each 8-bit timer/event counter module has multiplexer, 8-bit timer data register, 8-bit
counter register, mode register, input capture register, comparator. For PWM, it has PWM register
(T1PPR, T1PDR, T1PWHR).
It has seven operating modes:
-
8 Bit Timer/Counter Mode
-
8 Bit Capture Mode
-
8 Bit Compare Output Mode
-
16 Bit Timer/Counter Mode
-
16 Bit Capture Mode
-
16 Bit Compare Output Mode
-
PWM Mode
Note> TxDR must be set to higher than 0x03 for guaranteeing operation.
The timer/counter can be clocked by an internal or external clock source (external EC0). The clock
source is selected by clock select logic which is controlled by the clock select (T0CK[2:0], T1CK[1:0]).
- TIMER0 clock source : fX/2, 4, 16, 64, 256, 1024, 4096, EC0
- TIMER1 clock source : fX/1, 2, 16, T0CK
In the capture mode, by INT0, INT1, the data is captured into Input Capture Register. The TIMER 0
outputs the compare result to T0 port in 8/16-bit mode. Also the timer 1 outputs the result T1 port in
the timer mode and the PWM wave form to PWM3 in the PWM mode.
