Notes
1. RSTA specifies the read or write mode of register RSTA: 0 = write mode; 1 = read mode. RSTA is used only with the
2. Read mode protocol for serial interfaces.

CB = control byte.
RV = register value.
S = start data transmission.
CBn = control byte that points to address n.
RVn = register value for register of address n.
RV(n + 1) = register value for register of address n + 1.
P = stop data transmission.
