• Manufacturer Part Number: w925e625
• Description: 8-bit Cid Microcontroller
• Manufacturer: ETC-unknow

T0S0-1&T1S0-1: Timer0 & Timer1 clock source mode select bits. These bits determine the timer0 &
DIVS: Divider clock source control bit 1:
CLOCK CONTROL2
ENBUZ: When ENBUZ=1 the BUZ pin works as buzzer output, otherwise BUZ pin is in floating state.
BUZSL: Buzzer output selection. When BUZSL=0 BUZ is the output of octave tone. When BUZZL=1,
KT1-0:
PORT 1
P1.7-0: P1 can be selected as input or output mode by the P1IO register, at initial reset, P1IO is set
M /S:
to 1, so P1 is used as input mode . When P1IO is set to 0, the P1 is used as CMOS output
mode. When P1EF are set and P1IO are set as input mode, P1 can be used as external
interrupt source. The functions are listed below.
DIVS = 0 : Fs/2
DIVS= 1 : Fs/2
System clock source control bit :
KT1
BUZ is the output of key tone.
Key tone frequency sources from divider. When divider is enable, KT1 and KT0 determines
the key tone frequency.
