9.1 Functions of Clock Output/Buzzer Output Controller
supply to peripheral ICs.
R01UH0004EJ0401 Rev.4.01
Jul 2, 2010
The clock output/buzzer output controller is mounted onto all 78K0R/Lx3 microcontroller products.
The clock output controller is intended for carrier output during remote controlled transmission and clock output for
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.
PCLBUZ0 outputs a clock selected by clock output select register 0 (CKS0).
PCLBUZ1 outputs a clock selected by clock output select register 1 (CKS1).
Figure 9-1 shows the block diagram of clock output/buzzer output controller.
Note
The PCLBUZ0 and PCLBUZ1 pins can output a clock of up to 10 MHz at 2.7 V ≤ V
exceeding 5 MHz at V
