RZ/G1E PinMultiplexing on SODIMM
The RZ/G1E CPU IO pins have many alternate functions and can be configured to any one of the alternate functions based on the requirement. Also most of
the RZ/G1E
CPU’s IO pins can be configured as GPIO if required.
The below table provides the details of RZ/G1E CPU pin connections to the SODIMM edge
connector with selected pin function highlighted and available alternate functions. This table has been prepared by referring Renesas
’s
RZ/G1E Hardware
User’s Manual
.
Important Note: It is strongly recommended to use the pin function same as selected in the SODIMM SOM Edge connector
for iWave’s BSP reusability and to
have compatible SODIMM modules in future for upgradability.
