35.16.1 Static Memory Controller (SMC) User Interface
The SMC is programmed using the registers listed in the following table. For each Chip Select, a set of four registers
is used to program the parameters of the external device connected on it. In the Register Summary
, “CS_number”
denotes the Chip Select number. 16 bytes (0x10) are required per Chip Select.
