29.16 Static Memory Controller (SMC) User Interface
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.
