1. INT1 Base Timer reset does not generate a Base Timer interrupt,INT1 may generate an interrupt if enabled.
The G1BTRR register provides the capability to reset the base timer when the base timer count value
matches the value stored in the G1BTRR register. The G1BTRR register is enabled by the RST4 bit in
the G1BCR0 register. This function is identical in operation to the G1PO0 base timer reset that is
enabled by the RST1 bit in the G1BCR0 reigster. If the free-running operation is not selected, the
channel 0 can be used for a waveform generation when the base timer is reset by the G1BTRR
register. Do not enable the RST1 bit and RST4 bit simultaneously.
