Description
Transmit Data/Write Enable.
Data input from DTE TXD pin in serial mode. Active low write-enable pin in paral-
lel mode.
Clear-to-Send/Chip Select.
Active low clear-to-send (for flow control) in serial mode. Active low chip select in
parallel mode.
Reset Input.
An active low input that is used to reset all control registers to a defined initialized
state.
Analog Output/Interrupt Output.
Analog output in serial mode. Active low interrupt output in parallel mode.
Interrupt Output/Data Bit.
Active low interrupt output in serial mode. Bidirectional parallel bus data bit 0 in
parallel mode.
Ring Indicator/Data Bit.
The RI on (active low) indicates the presence of an ON segment of a ring signal
on the telephone line. Bidirectional parallel bus data bit 1 in parallel mode.
EEPROM Serial Data Input/Output/Data Bit.
Bidirectional Input/Output to SPI EEPROM in serial mode. Bidirectional parallel
bus data bit 2 in parallel mode.
Bias Voltage.
This pin provides decoupling for the power supply.
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor, C1.
Escape/Data Bit.
Hardware escape in serial mode. Bidirectional parallel bus data bit 3 in parallel
mode.
Carrier Detect/Data Bit.
Active low-carrier detect in serial mode. Bidirectional parallel bus data bit 4 in par-
allel mode.
EEPROM Clock/Data Bit.
Clock output for SPI EEPROM in serial mode. Bidirectional parallel bus data bit 5
in parallel mode.
