Figure 5. Example 1 of a Daisy-Chain Data Sequence
W/WD0 = 32-bit word with a write command; WD0 writes data for device 0. The 0 refers to the position in the daisy chain (0 is closest
to the bus master). Devices 1 and 2 are devices further down the chain.
R/RD2 = 32-bit word with a read command; RD2 reads data from device 2.
X = Don’t care (for X in the data or command position).

W/WD0 = 32-bit word with a write command; WD0 writes data for device 0. The 0 refers to the position in the daisy chain (0 is closest

R/RD2 = 32-bit word with a read command; RD2 reads data from device 2.
