Figure 19. MAX11014/MAX11015 I²C Default Read Timing
Command Byte
Begin a write or read to the MAX11014/MAX11015 by
writing a command byte at DIN/SDA. Set bit C7 to 1 for
a read operation. Set bit C7 to 0 for a write operation.
See Table 1. The remaining bits, C6–C0, determine the
register accessed by the command byte. Table 2 indi-
cates the register’s read/write access. C7 is the MSB of
the command byte and C0 is the LSB. Following the
command byte, write or read 2 data bytes to/from bits
D15–D0. D15 is the MSB of the 2 data bytes and D0 is
the LSB. See Figures 9, 10, 17, 18, and 19 and the
Register Descriptions section.
