11.4 Operations of Clock Output/Buzzer Output Controller
11.4.1 Operation as output pin

Oct 01, 2010
One pin can be used to output a clock or buzzer sound.
The PCLBUZ0 pin outputs a clock/buzzer selected by the clock output select register 0 (CKS0).
The PCLBUZ1 pin outputs a clock/buzzer selected by the clock output select register 1 (CKS1).
The PCLBUZn pin is output as the following procedure.
<1> Select the output frequency with bits 0 to 3 (CCSn0 to CCSn2, CSELn) of the clock output select register (CKSn)
<2> Set bit 7 (PCLOEn) of the CKSn register to 1 to enable clock/buzzer output.
Remarks 1. The controller used for outputting the clock starts or stops outputting the clock one clock after enabling or
of the PCLBUZn pin (output in disabled status).
Clock output
2. n = 0:
disabling clock output (PCLOEn bit) is switched. At this time, pulses with a narrow width are not output.
Figure 11-4 shows enabling or stopping output using the PCLOEn bit and the timing of outputting the clock.
