The above applies to the following conditions.
The RST4 bit in the G1BCR0 register is set to "0" (the base timer is not reset by matching the G1BTRR register)
The RST1 bit in the G1BCR1 register is set to "0" (the base timer is not reset by matching the G1PO0 register)
The UD1 to UD0 bits in the G1BCR1 register are set to "002" (counter increment mode)
