Configuration/Setup Bytes (Write Cycle)
A write cycle begins with the bus master issuing a
START condition followed by seven address bits (Figure
7) and a write bit (R/W = 0). If the address byte is suc-
cessfully received, the MAX11612–MAX11617 (slave)
issues an acknowledge. The master then writes to the
slave. The slave recognizes the received byte as the
set-up byte (Table 1) if the most significant bit (MSB) is
1. If the MSB is 0, the slave recognizes that byte as the
configuration byte (Table 2). The master can write either
one or two bytes to the slave in any order (setup byte,
then configuration byte; configuration byte, then setup
byte; setup byte or configuration byte only; Figure 9). If
the slave receives a byte successfully, it issues an
acknowledge. The master ends the write cycle by issu-
ing a STOP condition or a repeated START condition.
When operating in HS mode, a STOP condition returns
the bus into F/S mode (see the
HS Mode section).

REG
Register bit. 1 = setup byte, 0 = configuration byte (Table 2).

SEL0
Three bits select the reference voltage and the state of AIN_/REF
(MAX11612/MAX11613/MAX11616/MAX11617) or REF (MAX11614/MAX11615) (Table 6).
Default to 000 at power-up.
3
CLK
1 = external clock, 0 = internal clock. Defaults to 0 at power-up.
2
BIP/UNI
1 = bipolar, 0 = unipolar. Defaults to 0 at power-up (see the Unipolar/Bipolar section).
1
RST
1 = no action, 0 = resets the configuration register to default. Setup register remains unchanged.
0
X
Don’t-care bit. This bit can be set to 1 or 0.
