Section 16 Timer X1
16.1
Overview
Timer X1 is capable of outputting two different types of independent waveforms using a 16-bit
free running counter (FRC) as the basic means and it is also applicable to measurements of the
durations of input pulses and the cycles external clocks.
16.1.1
Features
Timer X1 has the following features:
•
Four different types of counter inputting clocks.
Three different types of internal clocks (
φ
/4,
φ
/16 and
φ
/64) and the DVCFG.
•
Two independent output comparing functions
Capable of outputting two different types of independent waveforms.
•
Four independent input capturing functions
The rising edge or falling edge can be selected for use. The buffer operation can also be
designated.
•
Counter clearing designation is workable.
The counter readings can be cleared by compare match A.
•
Seven types of interrupt causes
Comparing match
×
2 causes, input capture
×
4 causes and overflow
×
1 cause are available for
use and they can make respective interrupt requests independently.
