Memory and Peripheral Address and Data Bus
Memory and Peripheral Address and Data Bus
Memory and Peripheral Address and Data Bus
Address/Data Bus Strobe (data bus selected if low)
The digital negative supply rail (ground)
For manufacturer's use only. Connect to DVSS directly
HDLC Chip Reset
Do not make any connection to this pin
Do not make any connection to this pin
API/RS232 Port 2 Rx Data (inactive = high)
API/RS232 Port 2 Tx Data (high when inactive)
Do not make any connection to this pin
Do not make any connection to this pin
ISDN Line Failure Indicator
The digital positive supply rail. Levels and voltages are
dependent upon this supply. This pin should be decoupled
to DVSS by a capacitor
POTS Port Ringing Generator (low when not ringing)
POTS Port Ringing Generator (high when not ringing)
POTS Port Line Voltage Adjustment (low when sending FSK
to a Caller Display unit. If low, it makes the SLIC present a
high impedance to the POTS line)
POTS Port Hook Switch Status Detector
(on-hook = low)
For manufacturers’ use only. Connect to DVSS directly
CMX605 C-BUS Interface - Reply Data
CMX605 C-BUS Interface - Command Data
CMX605 C-BUS Interface - Serial Clock
The positive analog supply rail. Levels and voltages are
dependent upon this supply. This pin should be decoupled
to AVSS by a capacitor
A/D Reference Voltage. Connect to AVDD directly
The negative analog supply rail (ground)
CMX605 C-BUS Interface (chip select for POTS Port)
Do not make any connection to this pin
D/A Reference Voltage. Connect to AVDD directly
D/A Reference Voltage. Connect to AVSS directly
For manufacturer's use only. Connect to DVSS directly
API Interrupt (inactive = high)
CMX605 C-BUS Interface - Interrupt (inactive = high)
