Bit
Bit Name Initial Value R/W Description
7
ICPE1
0
R/W Input Capture Control
6
ICPE0
0
R/W A function of channel 2 only: determines whether
the input capture function can be used, and when
used, whether or not to enable interrupts.
Use the CKEG1 and CKEG0 bits to designate
use of either the rising or falling edge of the TCLK
pin to set the value of TCNT_2 in TCPR_2.
00: Input capture function is not used.
01: Setting prohibited
10: Input capture function is used. Interrupt due to
ICPF (TICPI2) are not enabled.
11: Input capture function is used. Interrupt due to
ICPF (TICPI2) are enabled.
5
UNIE
0
R/W Underflow Interrupt Control
Controls enabling of interrupt generation when
the status flag (UNF) indicating TCNT_2
underflow has been set to 1.
0: Interrupt due to UNF (TUNI2) is not enabled.
1: Interrupt due to UNF (TUNI2) is enabled.
4
CKEG1
0
R/W Clock Edge
3
CKEG0
0
R/W Select an input edge of the external clock when
the external clock is selected, or when the input
capture function is used.
00: Count/capture register set on rising edge
01: Count/capture register set on falling edge
1X: Count/capture register set on both rising and
falling edge
Note: X: Don’t care.
