11.0. MMC/SD connector
The BIG8051 development system is capable of reading memory cards due to the on-board MMC/SD connector. Memory
card communicates with the microcontroller through the microcontroller pins used for serial communication. In order to
establish connection between MMC/SD cards and the microcontroller, it is necessary to set switches 1, 3 and 5 (optionally
2, 4 and 6) on the DIP switch SW10, as well as switches 1 and 2 on the DIP switch SW14 to the ON position.
