3.1 char mmcInit (void);

Initialize the port, SPI, and the MMC card. You might need to adjust this routing if the library to adapt it to another type of MSP430 MCU or to another USART module. Also, some of the control signals can be set to a different port, if necessary.

Parameter: None
Return: Status Error or success code
