CHAPTER 7 CLOCK OUTPUT/BUZZER OUTPUT CONTROLLER

7.1 Functions of Clock Output/Buzzer Output Controller

The clock output controller is intended for carrier output during remote controlled transmission and clock output for
supply to peripheral ICs.
Buzzer output is a function to output a square wave of buzzer frequency.
One pin can be used to output a clock or buzzer sound.
Two output pins, PCLBUZ0 and PCLBUZ1, are available.
The PCLBUZn pin outputs a clock selected by clock output select register n (CKSn).
Figure 7-1 shows the block diagram of clock output/buzzer output controller.
