6.1.39 Bank 3 R9 (PRDAH: Most Significant Byte (Bit 9 ~ Bit 2) of
The content of Bank 3 of R9 is a period (time base) of PWMA Bit 9~Bit 2. The
frequency of PWMA is the reverse of the period.
6.1.40 Bank 3 RA (DTAH: Most Significant Byte (Bit 9 ~ Bit 2) of
A specified value keeps the PWMA output to remain high until the value matches with
TMRA.
6.1.41 Bank 3 RB (PRDBH: Most Significant Byte (Bit 9~Bit 2) of
The content of Bank 3 of R9 is a period (time base) of PWMB Bit 9~Bit 2. The
frequency of PWMB is the reverse of the period.
6.1.42 Bank 3 RC (DTBH: Least Significant Byte (Bit 9 ~ Bit 2) of
A specified value keeps the PWMB output to remain high until the value matches with
TMRB.
