/* Command style register access
Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the value bit that specifies the value that will be written into the selected bits of register.
eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered.
