4.13. PPG Communication Mode Data Bit Length Setting
Register : PCMDWD0 to PCMDWD3
The bit configuration of the PPG communication mode data bit length setting register is
shown.
The PPG communication mode data bit length setting register (PCMDWD) sets the bit length of the
High/Low format waveform output.
*: In PPG4 to PPG47, the communication function is not built into. The reading value of this bit is always
"0". This bit must always be written to "0".
