1. PI312 Overview
(9) Slave timer mode
In this mode, the channel 2 works relatively with the channel 1 operation.
The channel 1 is set as (3) Auto-reset universal counter mode.
Different from the (8) Slave counter mode, the channel 2 counts the internal clock
pulses in the interval of the channel 1 interrupt generation. The frequency of the internal
clock can be selected from 1, 10 or 100 kHz.
All other functions are the same as that of (8) Slave counter mode.
This mode is usable to measure the frequency of external pulses.
