8-BIT MICRO-CONTROLLER FOR TELECOM PRODUCT
Bit 3 ( PAB ) Prescaler assignment bit
0: TCC
1: WDT
Bit 4 ( TE ) : TCC signal source
0 : increment from low to high transition on TCC
1 : increment from high to low transition on TCC
Bit 5 ( TS ) : TCC signal source
0 : internal instruction cycle clock
1 : 32.768KHz
TS=0
16.38KHz
SYS clock
TS=1
no clock
32.768KHz
Green mode
Normal mode
Bit 6: (default 1)
unused
Bit 7: (default 1)
unused
CONT register is readable and writable
IOC5 ~ IOC9
( I/O Port Control Register )
Five I/O direction control registers.
“1” put the relative I/O pin into high impedance, while “0” put the relative I/O pin as output.
User can see IOCB register how to switch to normal I/O port.
IOCA
(CALLER ID RAM,IO ,PAGE Control Register)(read/write,initial “00000000”)

Bit0 PAGE : change IOCB ~ IOCE to another page , 0/1 => page0 / page1
Bit3~Bit1:”000" to “011” are four blocks of CALLER ID RAM area.
Bit4:port7 low nibble switch, 0/1= normal I/O port/SEGMENT output .
Bit5: high nibble switch
Bit6:port8 low nibble switch, 0/1= normal I/O port/SEGMENT output .
Bit7: high nibble switch
