Configuration/Setup Bytes (Write Cycle)
A write cycle begins with the bus master issuing a
START condition followed by 7 address bits (Figure 7)
and a write bit (R/W = 0). If the address byte is success-
fully received, the MAX11646/MAX11647 (slave) issue
an acknowledge. The master then writes to the slave.
The slave recognizes the received byte as the setup
byte (Table 1) if the most significant bit (MSB) is 1. If the
MSB is 0, the slave recognizes that byte as the configu-
ration byte (Table 2). The master can write either 1 or 2
bytes to the slave in any order (setup byte then configu-
ration byte, configuration byte then setup byte, setup
byte or configuration byte only; see Figure 9). If the
slave receives a byte successfully, it issues an acknowl-
edge. The master ends the write cycle by issuing 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 (see Table 2).

4
SEL0
Three bits select the reference voltage (Table 6). Default to 000 at power-up.
3
CLK
1 = external clock, 0 = internal clock. Defaulted to 0 at power-up.
2
BIP/UNI
1 = bipolar, 0 = unipolar. Defaulted 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.
