Controls if the device responds to one or two device
addresses (see the Memory Description section and
Table 5).
Controls the means by which Main and Auxiliary Device
addresses are set (see the Memory Description section
and Table 5).
Controls auxiliary write protect. See the Memory
Description section.
Controls main write protect. See the Memory Description
section.
Configures buffer 1 with OUT1 = MINT +
(INV1 [XOR] IN1).
Configures buffer 2 with OUT2 = INV2 [XOR] IN2.
Contains Main Device address if the bit ADFIX = 1. If
ADFIX = 0, then address A2h is used.
Contains bits used to perform right shift operations on the
A/D output converter. See the Right Shift A/D Conversion
Result section.
