General-purpose I/O port 3 bit 2.
UART D Serial Output. This pin is used to transmit serial data out
to the communication link.
Determines PIN 107 and 108 multi-function select. During power-
on reset, this pin is pulled down internally and is defined as
BEEP function and power LED enable. A 1 kΩ is reserved to pull
down and a 1 kΩ resistor is recommended if intending to pull up
to enable GPIO output.
General-purpose I/O port 4 bit 2.
UART E Serial Output. This pin is used to transmit serial data out
to the communication link.
General-purpose I/O port 5 bit 2.
UART F Serial Output. This pin is used to transmit serial data out
to the communication link.
Write data. This logic low open drain writes pre-compensation
serial data to the selected FDD. An open drain output.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
General-purpose I/O port 1 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
General-purpose I/O port 3 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
General-purpose I/O port 4 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
General-purpose I/O port 5 bit 1.
Data Carrier Detect. An active-low signal indicates the modem or
data set has detected a data carrier.
Write enable. An open drain output.
Ring Indicator. An active-low signal indicates that a ring signal is
being received from the modem or data set.
Ring Indicator. An active-low signal indicates that a ring signal is
being received from the modem or data set.
General-purpose I/O port 1 bit 0.
Ring Indicator. An active-low signal indicates that a ring signal is
being received from the modem or data set.
