Description
Counter Clear 1 and 0
These bits specify the clearing conditions of TCNTV.
00: Clearing is disabled
01: Cleared by compare match A
10: Cleared by compare match B
11: Cleared on the rising edge of the TMRIV pin.
The operation of TCNTV after clearing depends on TRGE
in TCRV1.
Clock Select 2 to 0
These bits select clock signals to input to TCNTV and the
counting condition in combination with ICKS0 in TCRV1.
Refer to table 11.2.
