Description
Counter Start 2 to 0
These bits select operation or stoppage for TCNT.
If 0 is written to the CST bit during operation with the
TIOC pin designated for output, the counter stops but
the TIOC pin output compare output level is retained. If
TIOR is written to when the CST bit is cleared to 0, the
pin output level will be changed to the set initial output
value.
0: TCNT_2 to TCNT_0 count operation is stopped
1: TCNT_2 to TCNT_0 performs count operation
Description
Reserved
These bits are always read as 0. The write value should
always be 0.
Counter Start U5
Selects operation or stoppage for TCNTU_5.
0: TCNTU_5 count operation is stopped
1: TCNTU_5 performs count operation
Counter Start V5
Selects operation or stoppage for TCNTV_5.
0: TCNTV_5 count operation is stopped
1: TCNTV_5 performs count operation
Counter Start W5
Selects operation or stoppage for TCNTW_5.
0: TCNTW_5 count operation is stopped
1: TCNTW_5 performs count operation
