5.15.4 Register Read/Write

0 W/R RA4 RA3 RA2 RA1 RA0 0
The Read/Write informs the command decoder that a register access is required. During a read operation, the ad-
dressed register is loaded into the device’s output buffer and clocked out by SCLK. During a write operation, the
data is clocked into the input buffer and transferred to the addressed register upon completion of the 24th SCLK.
W/R
Write/Read control
0 = Read register
1 = Write register
RA[4:0]
Register address bits (bits 5 through 1) of the read/write command.
