C1[7] -> C1[6] … C1[0] -> C2[7] -> C2[6] … C2[0] -> C3[7] -> C3[6] … C3[0]
-> C4[7] -> C4[6] … C4[0]. That is, C1[7] bit is sent first, then C1[6] and so on.
If <D3[7:0]> <D2[7:0]> <D1[7:0]> <D0[7:0]> is the data read, then D0 is
sent from module first, then D1 and so on.
D0[7] -> D0[6] … D0[0] -> D1[7] -> D1[6] … D1[0] -> D2[7] -> D2[6] … D2[0]
-> D3[7] -> D3[6] … D3[0]
4.5.4 Frame read (Slave Read)
This is same as master read, except that bit 3 of C1 is set and the Address phase is
skipped. The sequence of command transactions (with no failure from the slave) for
a Frame Read is as described in the figure below.
