11.6 Timer 1
11.6.1 Overview
The 16-bit timer 1 consists of multiplexer, timer 1 A data register high/low, timer 1 B data register high/low and timer 1
control register high/low (T1ADRH, T1ADRL, T1BDRH, T1BDRL, T1CRH, T1CRL).
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 1 can be clocked by an internal or an external clock source (EC1). The clock source is selected by
clock selection logic which is controlled by the clock selection bits (T1CK[2:0]).

TIMER 1 clock source: f

/(1, 2, 4, 8, 64, 512, 2048), EC1
In the capture mode, by EINT11, the data is captured into input capture data register (T1BDRH/T1BDRL). Timer 1
outputs the comparison result between counter and data register through T1O port in timer/counter mode. Also Timer
1 outputs PWM wave form through PWM1O port in the PPG mode.

11.6.2 16-bit Timer/Counter Mode
The 16-bit timer/counter mode is selected by control register as shown in Figure 11.14.
The 16-bit timer has counter and data register. The counter register is increased by internal or external clock input.
Timer 1 can use the input clock with one of 1, 2, 4, 8, 64, 512 and 2048 prescaler division rates (T1CK[2:0]). When the
value of T1CNTH, T1CNTL and the value of T1ADRH, T1ADRL are identical in Timer 1 respectively, a match signal is
generated and the interrupt of Timer 1 occurs. The T1CNTH, T1CNTL value is automatically cleared by match signal.
It can be also cleared by software (T1CC).
The external clock (EC1) counts up the timer at the rising edge. If the EC1 is selected as a clock source by T1CK[2:0],
EC1 port should be set to the input port by P13IO bit.
