20.14 Static Memory Controller (SMC) User Interface
The SMC is programmed using the registers listed in Table 20-8. For each chip select, a set of four registers is used to pro-
gram the parameters of the external device connected on it. In Table 20-8, “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.
