CHAPTER 15 BUZZER OUTPUT

15.3Pin of the Buzzer Output

The pin related to the buzzer output is P37/BZ/PPG.

■P37/BZ/PPG Pin

The P37/BZ/PPG pin works as a general-purpose I/O (P37) pin, output pin for the buzzer output (BZ), or output pin for the 12-bit PPG (PPG).

●BZ pin

The BZ pin outputs the square wave for the buzzer of the frequency having been specified for the BZ pin. When a buzzer output frequency is specified (other than BZCR:BZ2,BZ1,BZ0=000B), the P37/BZ/PPG pin automatically works as the BZ pin regardless of the value of output latch. Even if the PPG output has been enabled, it works as the BZ pin that has higher priority.

Note:

If pull-up resistor supported is specified by the pull-up setting register, the state of the pin in stop mode (SPL=1) is not Hi-Z but "H" level (pull-up state). During a reset, however, the pull-up is disabled and the state is Hi-Z.
