FUNCTION
RTSB#
ENGMTO
UART B Request To Send. An active low signal informs the modem
or data set that the controller is ready to send data.
Power on setting pin for enabling Watch Dog timer and its
countdown. This pin is pulled down internally and provides the
power-on value for bit 0 of CR30 and a count value of 0x0A for CRF6
in logical device 8. A 4.7 k
is recommended if intends to pull up.
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 PNPCSV#, which provides the power-on value for CR24
bit 0 (PNPCSV#). A 4.7 k
is recommended if intends to pull up.
(clear the default value of FDC, UARTs, PRT, Game port and MIDI
port)
UART B Data Terminal Ready. An active low signal informs the
modem or data set that controller is ready to communicate.
Serial Input. It is used to receive serial data through the
communication link.
UART A Serial Output. It 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, which provides the power-on value for CR24 bit
2 (ENKBC). A 4.7 k
resistor is recommended if intends to pull up.
(enable KBC)
UART B Serial Output.
During power-on reset, this pin is pulled down internally and is
defined as PEN48, which provides the power-on value for CR24 bit 6
(EN48). A 4.7 k
resistor is recommended if intends to pull up.

Data Carrier Detect. An active low signal indicates the modem or
data set has detected a data carrier.
Ring Indicator. An active low signal indicates that a ring signal is
being received from the modem or data set.
