12.2 Configuration of Clock Output/Buzzer Output Controller
12.3 Register to Control Clock Output/Buzzer Output Controller
(1) Clock output select register (CKS)
The clock output/buzzer output controller consists of the following hardware.
The following three registers are used to control the clock output/buzzer output controller.
• Clock output select register (CKS)
• Port mode register (PM7)
• Port 7 (P7)
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 input clears CKS to 00H.
