X : Don’t care, − : No change
Example: To generate 1/4 duty 62.5 kHz pulses (at f
To obtain a frequency of 62.5 kHz, the pulse cycle t should be: t = 1/62.5 kHz = 16 μs
φT1 (= (16/fc)s (at f
Therefore set TA1REG to 40 (28H)
The duty is to be set to 1/4: t × 1/4 = 16 μs × 1/4 = 4 μs
Therefore, set TA0REG = 10 = 0AH
Calculate the value that should be set in the timer register.

Stop TMRA0 and TMRA1 and clear it to “0”.
Set the 8-bit PPG mode, and select φT1 as input clock.
Write 0AH.
Write 28H.
Set TA1FF and set inversion to enable.
Writing “10” provides negative logic pulse.
Set PC1 to TA1OUT pin.
Start TMRA0 and TMRA1 counting.
