The MAX1385/MAX1386 use read and write command
bytes. The command byte consists of 8 bits and contains
the address of the register (C7–C0, see Figures 18 and
19). The command byte also communicates to the
device whether a read or write operation occurs. See the
Register Description section for details on how to access
specific registers through the command byte.
Data bytes are clocked in/out of the device with the
most significant bit first and the least significant bit last
(D15–D0, see Figures 18 and 19). See the Register
Description section for a description of data bytes for
each register.
