Description
Input Capture Control
These bits, provided in channel 2 only, specify whether
the input capture function is used, and control enabling
or disabling of interrupt generation when the function is
used.
The CKEG bits specify whether the rising edge or falling
edge of the TCLK pin is used to set the TCNT2 value in
TCPR2.
The TCNT2 value is set in TCPR2 only when the ICPF
bit in TCR2 is 0. When the ICPF bit is 1, TCPR2 is not
set in the event of input capture.
00: Input capture function is not used.
01: Reserved (setting prohibited)
10: Input capture function is used, but interrupt due to
11: Input capture function is used, and interrupt due to
Underflow Interrupt Control
Controls enabling or disabling of interrupt generation
when the UNF status flag is set to 1, indicating TCNT
underflow.
0: Interrupt due to underflow (TUNI) is disabled
1: Interrupt due to underflow (TUNI) is enabled
Clock Edge 1 and 0
These bits select the external clock input edge when an
external clock that is input from the TCLK pin is selected
or the input capture function is used.
00: Count/input capture register set on rising edge
01: Count/input capture register set on falling edge
1X: Count/input capture register set on both rising and
input capture (TICPI2) is not enabled.
input capture (TICPI2) is enabled.
