Setup byte always starts with 1.
When [0,0], REF/AIN3 = AIN3, REF = V
When [0,1], REF/AIN3 = REF, REF = external reference.
When [1,0], REF/AIN3 = AIN3, REF = internal reference.
When [1,1], REF/AIN3 = REF, REF = internal reference.
(Table 3)
1 = internal reference always powered up.
0 = internal reference always powered down.
(Table 3)
0 = internal clock.
1 = external clock (MAX1361/MAX1362 use the SCL clock for conversions).
0 = unipolar.
1 = bipolar.
Selects unipolar or bipolar conversion mode. In unipolar mode, analog signal in 0 to V
can be converted. In differential bipolar mode, input signal can range from -V
When single-ended mode is chosen, the SE/
conversions are performed in unipolar mode.
1 = no action.
0 = resets
0 = no action.
1 = extends writing up to 13 bytes (104 bits) of alarm reset mask. Scans speed selection and
alarm thresholds. See the Configuring Monitor Mode section.

Initiate a read cycle to start a conversion sequence and
to obtain conversion results. See the Scan Modes
section for details on the channel-scan sequence. Read
cycles begin with the bus master issuing a START
condition followed by 7 address bits and a read bit
(R/W = 1). After successfully receiving the address byte,
the MAX1361/MAX1362 (slave) issue an ACK. The master
then reads from the slave. (See Figures 10–13.)
The result is transmitted in 2 bytes. The 1st byte con-
sists of a leading 1 followed by a 2-bit binary channel
address tag, a 12/10 bit flag (0 for the MAX1361/
MAX1362), 2 bits of 1s, the first 2 bits of the data result,
and the expected ACK from the master. The 2nd byte
