5.14.5 Register Read/Write
The Read/Write informs the command decoder that a register access is required. During a read operation, the ad-
dressed register is loaded into an output buffer and clocked out by SCLK. During a write operation, the data is
clocked into an input buffer and transferred to the addressed register upon completion of the 24
