Capture/Compare Channel Operation
PS025011-1010
One-Shot Compare Operation
Reload
0H
The Multi-Channel timer supports four Capture/Compare channels: CHA, CHB, CHC,
and CHD. Each channel has the following features:
•
•
Each channel is configured to operate in either ONE-SHOT Compare, CONTINUOUS
Compare, PWM Output, or Input CAPTURE mode.
In One-Shot compare operation, a channel interrupt is generated when the channel
compare value matches the timer count. The channel event flag (CHyEF) is set in the
Channel Status1 register (MCTCHS1) to identify the responsible channel. Then the
channel is automatically disabled. The timer continues counting according to the
programmed mode. If the timer channel output alternate function is enabled, the channel
output pin (TOutA, B, C, or D) changes state for one system clock cycle (from Low to
High then back to Low or High to Low then back to High as determined by the CHPOL
bit) on match.
A 16-bit Capture/Compare Register (MCTCHyH and MCTCHyL registers) used to
capture input event times or to generate time intervals. Any user software update of
the Capture/Compare Register value when the timer is running takes effect only at the
end of the counting cycle, not immediately. The end of the counting cycle is when the
counter transitions from the Reload value to 0 (count modulo mode) or from 1 to 0
(count up/down mode).
A dedicated bidirectional pin (TInA, B, C, or D) that can be configured for the input
capture function or to generate an output compare match or one-shot pulse.
