Description
9
ADC0
I
Analog-to-Digital converter Input. (0 to 3v).
10
ADC2
I
Analog-to-Digital converter Input. (0 to 3v).
11
GPI7
I
General-Purpose Input.
12
GPI9
I
General-Purpose Input.
13
TDO
O
JTAG Data Output.
14
NTRST
I/O
JTAG Reset (Active Low).
15
GPS-PPS
O
GPS PPS - Pulse Per Second.
16
GPS-TX
O
GPS - Transmit Data.
17
-DTR_1
I
Data Terminal ready. The DTE uses the -DTR_1 line to signal to the
module that it is ready to accept communication. The signal is also
used to signal to the module to terminate communication (hang-
up).
18
-RXD_1
O
Received Data. The gateway uses the RXD1 line to send data to
the DTE and to send gateway responses to the DTE. In command
mode, -RXD1 data presents the gateway responses to the DTE.
19
-TXD_1
I
Transmitted Data. The DTE uses the -TXD1 line to send data to the
gateway for transmission or to transmit commands to the
gateway. The DTE holds this circuit in mark state when no data is
being transmitted or during intervals between characters.
20
-RTS_1
I
"Request to Sent (Active Low). -RTS1 signal is used for hardware
flow control. -RTS1 input ON (low) indicates that the DTE is ready
to send data to the device. In the command state, the device
ignores -RTS1.
21
-DCD_1
O
Data Carrier Detect (Active Low). DCD is controlled by processor.
You can program how DCD is set.
22
-CTS_1
O
Clear to Send (Active Low). -CTS_1 is controlled by the gateway to
indicate whether or not the gateway is ready to receive data from
the DTE on the -TXD_1 input signal.
23
GPO4
O
General-Purpose Output.
24
GPO3
O
General-Purpose Output.
25
GPO2
O
General-Purpose Output.
26
GPO1
O
General-Purpose Output.
27
27 GND Logic Ground.
28
-RESET
I
Device Reset (with pull-up). The active low -RESET input resets the
device logic. -RESET is tied to VCC through a time-constant circuit
for proper reset of the device if -RESET is not being externally
driven.
29
BATT-IN
I
Battery Backup Input 3V.
30
USBH_DP
I/O
USB Host Data Positive. Positive pin of USB data pair.
