CHAPTER 9 12-BIT PPG TIMER
9.3 Pin of 12-bit PPG Timer
This section describes the pin associated with the 12-bit PPG timer and illustrates a
block diagram of circuitry terminating at the pin.
■ Pin Associated with the 12-bit PPG Timer
The pin associated with the 12-bit PPG timer is P37/BZ/PPG pin.
●
P37/BZ/PPG pin
This pin functions as a CMOS type (P37) general-purpose I/O port, further functioning as 12-bit PPG timer
output (PPG).
PPG:
By setting the output enable bit of the appropriate 12-bit PPG control register (RCR23:RCEN) to "1",
the pin functions as the PPG output pin through which the set cycle period and "H" width of PPG
pulse waveforms are output.
