DESCRIPTION
Transmit Data is the data input to the XE900SL10.
Received Data is the data output from the XE900SL10.
Clear to Send provides hardware flow control from the XE900SL10. The XE900SL10
drives /CTS high to signal the host to temporarily stop the flow of data into /TXD.
Request to Send provides hardware flow control from the host system. The host system
drives /RTS high to signal the XE900SL10 to temporarily stop the data flow onto /RXD.
DIO3 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900SL10.
DIO2 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900SL10.
DIO1 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900SL10.
DIO0 may be programmed as either a digital input or digital output. It connects directly to
the communications controller in the XE900SL10.
No Connection
Common voltage reference for the XE900SL10.
3.3 Volt power for the XE900SL10.
Analog Input 1 to the XE900SL10’s communications controller. ADC1 connects to an
internal 12-bit Analog to Digital Convertor. ADC1 may also be configured as a digital
input if no analog inputs are required.
Analog Input 0 to the XE900SL10’s communications controller. ADC0 connects to an
internal 12-bit Analog to Digital Convertor. ADC0 may also be configured as a digital
input if no analog inputs are required.
Provides an active high hardware reset to the XE900SL10.
