UART A Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
During power-on reset, this pin is pulled down internally and is
defined as FDC enable, which provides the power-on value for
CR24 bit 1. A 1 kΩ is reserved to pull down and a 1 kΩ resistor
is recommended if intends to pull-up to enable UART F.
UART B Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
General-purpose I/O port 1 bit 4.
UART C Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
General-purpose I/O port 3 bit 4.
UART D Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
General-purpose I/O port 4 bit 4.
UART E Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
General-purpose I/O port 5 bit 4.
UART F Data Terminal Ready. An active-low signal informs the
modem or data set that the controller is ready to communicate.
Direction of the head step motor. An open drain output.
Logic 1 = outward motion
Logic 0 = inward motion
