Data Set Ready. An active low signal indicates the modem or
data set is ready to establish a communication link and transfer
data to the UART.
General purpose I/O port 4 bit 6.
UART A Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
During power-on reset, this pin is pulled down internally(20K±30%)
and is defined as HEFRAS, which provides the power-on value
for CR26 bit 6 (HEFRAS).
kΩ is recommended if intends to pull up. (select 4EH as
configuration I/O port′s address)
General purpose I/O port 6 bit 5.
UART B Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
General purpose I/O port 4 bit 5.
UART A 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 6 bit 4.
UART B Data Terminal Ready. An active low signal informs the
modem or data set that controller is ready to communicate.
General purpose I/O port 4 bit 4.
Serial Input. It is used to receive serial data through the
communication link.
General purpose I/O port 6 bit 3.
Serial Input. It is used to receive serial data through the
communication link.
