DCD2#
78
RI2#
IN_t5V
Data Carrier Detect. An active low signal indicates the
modem or data set has detected a data carrier.
IN_t5V
Ring Indicator. An active low signal indicates that a ring
signal is being received from the modem or data set.
79
IRRX2
IN_ts5V
Infrared Receiver input.
80
IRTX2
OUT12
Infrared Transmitter Output.
81
CTS1#
IN_t5V
Clear To Send is the modem control input.
82
DSR1#
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.
83
RTS1#
I/O_8t5V-d100
UART 1 Request To Send. An active low signal informs the
modem or data set that the controller is ready to send data.
PS_CONF_2E
Power on configuration setting. Default PS_CONF_2E = 0,
setting the configuration to 0x4E. If PS_CONF_2E =1, setting
the configuration to 0x2E.
84
DTR1#
I/O_8t5V-d100
UART 1 Data Terminal Ready. An active low signal informs
the modem or data set that controller is ready to communicate.
PS_3E0_IRQA
Power setting pin to define the IRQA index.
Default PS_3E0_IRQA = 0, IRQB index is programmed by
register.
If PS_3E0_IRQA = 1, setting IRQA index to 0x3E0.
85
SIN1
IN_t5V
Serial Input. Used to receive serial data through the
communication link.
86
SOUT1
I/O_8t5V-d100
UART 1 Serial Output. Used to transmit serial data out to the
communication link.
PS_3F8_IRQA
Power setting pin to define the IRQA index.
Default PS_3F8_IRQA = 0, IRQA index is programmed by
register.
If PS_3F8_IRQA = 1, setting IRQA index to 0x3F8.
87
DCD1#
IN_t5V
Data Carrier Detect. An active low signal indicates the
modem or data set has detected a data carrier.
88
RI1#
IN_t5V
Ring Indicator. An active low signal indicates that a ring
signal is being received from the modem or data set.
