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.
RTSA#
43
I/O
8t
UART A Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
HEFRAS
During power-on reset, this pin is pulled down internally and is
defined as HEFRAS, which provides the power-on value for
CR26 bit 6 (HEFRAS). A 4.7 k
is recommended if intending to
pull up. (select 370H as configuration I/O port
s address)
RTSB#
50
I/O
8t
UART B Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
