11.7 Timer 2
11.7.1 Overview
The 16-bit timer 2 consists of multiplexer, timer 2 A data high/low register, timer 2 B data high/low register and timer 2
control high/low register (T2ADRH, T2ADRL, T2BDRH, T2BDRL, T2CRH, and T2CRL).
It has four operating modes:
−
16-bit timer/counter mode
−
16-bit capture mode
−
16-bit PPG output mode (one-shot mode)
−
16-bit PPG output mode (repeat mode)
The timer/counter 2 can be divided clock of the system clock selected from prescaler output and T1 A Match (timer 1 A
match signal). The clock source is selected by clock selection logic which is controlled by the clock selection bits
(T2CK[2:0]).

In the capture mode, by EINT12, the data is captured into input capture data register (T2BDRH/T2BDRL). In
timer/counter mode, whenever counter value is equal to T2ADRH/L, T2O port toggles. Also the timer 2 outputsPWM
wave form to PWM2O port in the PPG mode.
