12. PWC (Pulse Width Count) Timer
The PWC timer is a 16-bit multi-function up-count timer with an input signal pulse width measurement function.
The hardware includes a total of three channels, each with one 16-bit up-count timer, one input pulse divider
and divider ration control register, one measurement input pin, and one 16-bit control register. The following
functions are provided :
Timer functions :
An interrupt can be generated each time a set time interval elapses. A choice of three internal reference clocks
is available.
Pulse width measurement functions :
Measures the time between designated events on an externally input pulse signal. The reference clock is selected
from three internal clock signals.
Measurement modes : 1) H pulse width (
to ) /L pulse width (to )
2) Rise period (
to ) /fall period (to )
3) Measurement between edges (high or low to low or high)
An 8-bit input divider can divide the input pulse into 22n divisions (n
= 1, 2, 3, 4) and measure the divisions.
An interrupt can be generated when measurement is ended. Both one-time and continuous measurement are
enabled.
