The TRD0 register is incremented (the TRD1 is not used).
PWM period: 1/fk × (m+1)
Active level width of TRDIOA0 output: 1/fk × (m-n)
Active level width of TRDIOB0 output: 1/fk × (p-q)
1 (count starts) is written to the TSTART0 bit in the TRDSTR register.
• 0 (count stops) is written to the TSTART0 bit in the TRDSTR register
• When the CSEL0 bit in the TRDSTR register is set to 0, the count
• Compare match (The content of the TRDi register matches content
• The TRD0 register overflows

The count value can be read by reading the TRD0 register.
The value can be written to the TRD0 register.
