Write "0" by program if setting to "0"
i= 0 to 4, 8 to 10
j= 0 to 7
The above applies to the following conditions:
The CTS1 and CTS0 bits in the G1TMCRj registers are set to "012" (rising edge).
The PR bit is set to "0" (no prescaler used) and the GT bit is set to "0" (no gate
function used).
The RST2 and RST1 bits in the G1BCR1 register are set to "002" (no base timer
reset).
The UD1 and UD0 bits are set to "002" (counter increment mode).
To set the base timer to "000016" (setting the RST1 bit to "1" and the RST2 bit to "0")
when the base timer value matches the G1PO0 register setting, the base timer is set
to "000016" after it reaches the G1PO0 register value +2.
