IMPORTANT: Bits[31:27, 24:23, 14:12, and 7:3] in Table 1-58, page 136 are not used in this example.
The write waveform shown in Figure 1-90 illustrates an example with calibrated PHY read
data offset = 10. For a selected slot number of 1, nCK_PER_CLK of 4, the read data offset is:
Read data offset = Calibrated PHY read data offset + slot number
= 10 + 1 = 11
