Operation Of The Output Compare Module - Fujitsu FR60 Hardware Manual

14.4.3

Operation of the Output Compare Module

In the 16-bit output compare operation, an interrupt request flag can be set and the
output level can be reversed when the specified compare register value matches the 16-
bit free-run timer value.
■ Operation of the 16-bit Output Compare Module
The compare operation can be performed for each channel independently (when CMOD = 0).
Figure 14.4-2 shows a sample of the waveform that is output when compare registers 0 and 1 are used
(initial output value is "0").

The output level can be changed using two compare registers (when CMOD=1).
Figure 14.4-3 shows a sample of the waveform that is output when compare registers 0 and 1 are used
(initial output value is "0").
