state.
13
C2A
Isolation Capacitor 2A.
Connects to one side of the isolation capacitor, C2.
14
C1A
Isolation Capacitor 1A.
Connects to one side of the isolation capacitor, C1.
15
AOUT/INT
Analog Output/Interrupt Output.
Analog output in serial mode. Active low interrupt output in parallel mode.
16
INT/D0
Interrupt Output/Data Bit.
Active low interrupt output in serial mode. Bidirectional parallel bus data bit 0 in
parallel mode.
17
RI/D1
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.
18
SDI/EESD/D2
Serial Data In/EEPROM Serial Data Input/Output/Data Bit.
Serial Data In (to codec) output in serial mode. Bidirectional Input/Output to SPI
EEPROM in serial mode when pin 4 is pulled low during power up. Bidirectional
parallel bus data bit 2 in parallel mode.
22
ESC/D3
Escape/Data Bit.
Hardware escape in serial mode. Bidirectional parallel bus data bit 3 in parallel
mode.
23
DCD/D4
Carrier Detect/Data Bit.
Active low carrier detect in serial mode. Bidirectional parallel bus data bit 4 in par-
allel mode.
24
SDO/EECLK/D5
Serial Data Out/EEPROM Clock/Data Bit 5.
Serial Data Out (from codec) input in serial mode. Clock output for SPI EEPROM
in serial mode when pin 4 is pulled low during power up. Bidirectional parallel bus
data bit 5 in parallel mode.
