33
SOUT6
I/O_8t5V-d100
UART 6 Serial Output. Used to transmit serial data out to the
communication link.
PS_238_IRQF
Power setting pin to define the IRQF index.
Default PS_238_IRQF = 0, IRQF index is programmed by
register. If PS_238_IRQF = 1, setting IRQF index to 0x238
34
DCD6#
IN_t5V
Data Carrier Detect. An active low signal indicates the
modem or data set has detected a data carrier.
35
RI6#
IN_t5V
Ring Indicator. An active low signal indicates that a ring
signal is being received from the modem or data set.
36
CTS4#
IN_t5V
Clear To Send is the modem control input.
37
DSR4#
IN_t5V
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.
38
RTS4#
39
DTR4#
PS_LPC
40
SIN4
I/O_8t5V-d100
I/O_8t5V-d100
IN_t5V
UART 4 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
UART 4 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
Power on setting pin to define the ISA or LPC interface.
Default PS_LPC=0, ISA interface.
When PS_LPC=1, transfer to LPC interface.
Serial Input. Used to receive serial data through the
communication link.
41
SOUT4
I/O_8t5V-d100
UART 4 Serial Output. Used to transmit serial data out to the
communication link.
PS_2E8_IRQD
Power setting pin to define the IRQD index.
Default PS_2E8_IRQD = 0, IRQF index is programmed by
register.
If PS_2E8_IRQD = 1, setting IRQF index to 0x2E8.

IN_t5V
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.
Clear To Send is the modem control input.
