Register Descriptions
The MAX11014/MAX11015 communicate between the
internal registers and external bus lines through the serial
interface. Table 1 details the command bits (C7–C0) and
the data bits (D15–D0) of the serial input word. Table 2
details the command byte and the subsequent register
accessed. Tables 3–27 detail the various read and write
internal registers and their power-on reset states.
On power-up, the MAX11014/MAX11015 are in full
power-down mode (see the
SHUT (Write)
section). To
