Serial Input. This pin is used to receive serial data through the
communication link.
General-purpose I/O port 5 bit 3.
Serial Input. This pin is used to receive serial data through the
communication link.
Step output pulses. This active low open drain output produces a
pulse to move the head to another track.
UART A Serial Output. This pin is used to transmit serial data out
to the communication link.
During power on reset, this pin is pulled down internally and is
defined as PENKBC, and the power-on values are shown at
CR24 bit 2. The PCB layout should reserve space for a 1-kΩ
resistor to pull down this pin to ensure the disabling of KBC, and
a 1-kΩ resistor is recommended to pull the pin up If wish to
enable KBC.
UART B Serial Output. This pin is used to transmit serial data out
to the communication link.
IR Transmitter output.
General-purpose I/O port 1 bit 2.
UART C Serial Output. This pin is used to transmit serial data out
to the communication link.
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.
