11.8 Timer 3, 4
11.8.1 Overview
Timer 3 and timer 4 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, comparator, 8-bit timer data register, 8-bit counter register,
control register and capture data register (T3CNT, T3DR, T3CAPR, T3CR, T4CNT, T4DR, T4CAPR, T4CR). For
PWM, it has PWM register (T4PPRL. T4PPRH, T4ADRL, T4ADRH, T4BDRL, T4BDRH, T4CDRL, T4CDRH,
T4DLYA, T4DLYB, T4DLYC).
It has five operating modes:
-
8-bit timer/counter mode
-
8-bit capture mode
-
16-bit timer/counter mode
-
16-bit capture mode
-
10-bit PWM mode
The timer/counter 3 and 4 can be clocked by an internal or an external clock source (EC3).
The clock source is
selected by clock selection logic which is controlled by the clock selection bits (T3CK[2:0], T4CK[3:0]). Also the
timer/counter 4 can use more clock sources than timer/counter 3.
- TIMER 3 clock source: f
X
/2, 4, 8, 32, 128, 512, 2048 and EC3
- TIMER 4 clock source: f
X
/1, 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048, 4096, 8192, 16384 and T3 clock
In the capture mode, by EINT0/EINT1, the data is captured into input capture data register (T3CAPR, T4CAPR).
In 8-bit timer/counter 3/4 mode, whenever counter value is equal to T3DR/T4DR, T3O/T4O port toggles. Also In
16-bit timer/counter 3 mode,
The timer 3 outputs the comparison result between counter and data register through T3O port.
The PWM wave
form to PWMAA, PWMAB, PWMBA, PWMBB, PWMCA, PWMCB Port (6-channel) in the PWM mode.
