F81218
48
DSR3#
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.
49
RTS3#
I/O_8t5V-d100
UART 3 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
PS_CONF_KE
Y0
Power on configuration setting pin. As for detail description,
please refer to register description.
50
DTR3#
I/O_8t5V-d100
UART 3 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
PS_WDT
Power on setting pin to enable the watch dog timer.
Default PS_WDT=0, WDT time programmed by register.
When PS_WDT=1, WDT time is defined as 10 sec.
51
SIN3
IN_t5V
Serial Input. Used to receive serial data through the
communication link.
52
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.
53
DCD3#
IN_t5V
Data Carrier Detect. An active low signal indicates the
modem or data set has detected a data carrier.
54
RI3#
IN_t5V
Ring Indicator. An active low signal indicates that a ring
signal is being received from the modem or data set.
62
CTS5#
IN_t5V
Clear To Send is the modem control input.
63
DSR5#
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.
64
RTS5#
I/O_8t5V-d100
UART 5 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
65
DTR5#
I/O_8t5V-d100
UART 5 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
66
SIN5
IN_t5V
Serial Input. Used to receive serial data through the
communication link.
