12.2 Configuration of Clock Output/Buzzer Output Controller
12.3 Registers Controlling Clock Output/Buzzer Output Controller
308
The clock output/buzzer output controller includes the following hardware.
The following two registers are used to control the clock output/buzzer output controller.
• Clock output selection register (CKS)
• Port mode register 14 (PM14)
(1) Clock output selection register (CKS)
This register sets output enable/disable for clock output (PCL) and for the buzzer frequency output (BUZ), and
sets the output clock.
CKS is set by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation sets CKS to 00H.
