High speed SPI
The High Speed Serial Peripheral Interface (HS_SPI) can interface the serial data
transfer. HS_SPI has two 8-bit shift registers for transmission and receiving,
respectively. During an SPI transfer, data is simultaneously transmitted (shifted out
serially) and received (shifted in serially). HS_SPI supports the protocols for National
Semiconductor Microwire and Motorola Serial Peripheral Interface.

WLAN connectors
In addition to the wired Ethernet interface, the ConnectCore Wi-9M 2443 module
also offers an integrated dual-diversity 802.11a/b/g interface with data rates up to
54 Mbps. Two U.FL antenna connectors are provided on the module. For the Connect
Core Wi-9M 2443, attach the antennas with the U.FL-RP-SMA FEMALE Cable to the
