2.10 802.11 WIRELESS CONNECTIVITY
The Multimedia Expansion Board has 802.11 wireless connectivity, which is provided
by the Microchip MRF24WBOMA module, as shown in Figure 2-24. The PIC32 micro-
controller uses a SPI bus interface to communicate to the MRF24WBOMA. The CPLD
needs to be properly configured for the PIC32 microcontroller to access the
MRF24WBOMA. For configuration information, see Section 2.12 “CPLD”.
