These are 16-bit registers that are used to set the period of the output pulses generated by PPG. The initial
value of them are undetermined, so that these registers must be written before starting an operation. Word
access to these registers are recommended. These registers are write-only.
Data transfer from period setting buffer register to period setting register will be at counter borrow or
trigger or retrigger if enabled.
Note:
In case of updating period setting buffer register, duty setting buffer register must be written after
writing to period setting buffer register. Only updating period setting buffer register is prohibited.
