Note that the serial module output is at 3.0V CMOS logic levels. Level conversion must be added to
interface with an RS-232 level compliant interface.
6.1.2
Three pins are provided to allow implementation of Bluetooth coexistence schemes, when the 802.11
module is collocated with a Bluetooth radio. These connect directly between the basebands of the two
radios to ensure minimum interference.
supported.
Coexistence requires that the Bluetooth radio meets at least version 1.2 of the Bluetooth standard and
supports Adaptive Frequency Hopping (AFH).
6.1.3
Twelve lines of programmable bi-directional input/outputs (I/O) are provided that can be accessed via
the UART port with the IO family of commands.
external equipment.
Each of the GPIO pins can be independently configured to be either an Input or Output. A selection of
ports can be accessed synchronously.
Four of the lines (GPIO 10-13) are shared with modem control functions.
implement a fully featured UART, then they cannot be used for GPIO.
6.1.4
The Wireless LAN module provides access to two 10-bit ADCs. These provide an input range of 0V to
3.0v.
Suitable external scaling and over-voltage protection should be incorporated in your design.
Please refer to the WISM ADC Application Note AN017 for information on interfacing the ADC pins.
