9.1. PMOD TM Interfaces
Two Digilent PMOD TM (Interface Type 2A, expanded SPI) connection headers are available on the RDK. These
interfaces can be access on the SPI bus using chip selects P71 (pin 28) for PMOD1 and P72 (pin 27) for PMOD2.
PMOD TM Interface connections are shown in

9.2. Application Header (WIFI Module)
The application header J6 can be fitted with a WIFI module. These devices can be accessed UART2 or the SPI bus
(CSI10) using chip select P73 (pin 26) on the RL78. WIFI interrupt requests can be received on INTP8 (pin 25) on the
RL78. As of November 2011, several WiFi modules were available and some units released for RL78 by Gainspan Corp.
and RedPine Signals were qualified, more information at :
