15.7 User Interface
The SMC is programmed using the registers listed in Table 15-8 on page 212. For each chip select, a set of four registers
is used to program the parameters of the external device connected on it. In Table 15-8 on page 212, “CS_number”
denotes the chip select number. Sixteen bytes (0x10) are required per chip select.
The user must complete writing the configuration by writing anyone of the Mode Registers.
