13.0. MMC/SD Connector
The MMC/SD connector enables the memory cards to be interfaced to the microcontroller in order to expand microcontroller memory.
To enable serial communication between the microcontroller and a memory card it is necessary to select microcontroller pins to be fed
with signal sent from the memory card. DIP switches SW14 and SW15 are used as pin selectors. Figure 13-3 illustrates the connection
between the MMC/SD connector and RG9, RE7, RG8, RG7 and RG6 microcontroller pins. Alternatively, pins RB15, RB14, RB13,
RB12 and RC3 can be used here as well.
