The SMC is programmed using the registers listed in 

. For each chip select, a set of 4 registers is used to program the 

parameters of the external device connected on it. In 

, “CS_number” denotes the chip select number. 16 bytes (0x10) 

are required per chip select.

The user must complete writing the configuration by writing any one of the SMC_MODE registers.
