Bit configuration and function vary depending on which channel is used.
Registers associated with the time measurement function should be set after setting registers associated with the base time.

The above applies to the following condition.
When the base timer matches the G1PO0 register and is set to "0000
bit to "1", and the RST4 and RST2 bits to "0"), the base timer is set to "0000
