25
SIN3
IN_t5V
Serial Input. Used to receive serial data through the
communication link.
26
SOUT3
I/O_8t5V-d100
UART 3 Serial Output. Used to transmit serial data out to the
communication link.
PS_3E8_IRQC
Power setting pin to define the IRQC index.
Default PS_3E8_IRQC = 0, IRQF index is programmed by
register.
If PS_3E8_IRQC = 1, setting IRQC index to 0x3E8.
27
DCD3#
IN_t5V
Data Carrier Detect. An active low signal indicates the
modem or data set has detected a data carrier.
28
RI3#

DSR2#
33
RTS2#
IN_t5V
IN_t5V
IN_t5V
I/O_8t5V-d100
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.
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.
UART 2 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
PS_CONF_KE
Y1
Power on configuration setting pin. As for detail description,
please refer to register description.
34
DTR2#
I/O_8t5V-d100
UART 2 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
PS_2E0_IRQB
Power setting pin to define the IRQB index.
Default PS_2E0_IRQB = 0, IRQB index is programmed by
register.
If PS_2E0_IRQB = 1, setting IRQB index to 0x2E0.
35
SIN2
IN_t5V
Serial Input. Used to receive serial data through the
communication link.
36
SOUT2
I/O_8t5V-d100
UART 2 Serial Output. Used to transmit serial data out to the
communication link.
PS_2F8_IRQB
Power setting pin to define the IRQB index.
Default PS_2F8_IRQB = 0, IRQB index is programmed by
register.
If PS_2F8_IRQB = 1, setting IRQB index to 0x2F8.
