23.15 Static Memory Controller (SMC) User Interface
The SMC is programmed using the registers listed in
gram the parameters of the external device connected on it. In
16 bytes (0x10) are required per chip select.
The user must complete writing the configuration by writing any one of the SMC_MODE registers.
