FUNCTION
5 — — 0 ADEN
Controls if the device responds to one or two device
addresses (see the Memory Description section and
Table 5).
4 — — 0 ADFIX
Controls the means by which Main and Auxiliary Device
addresses are set (see the Memory Description section
and Table 5).
3 — — 0 APEN
Controls auxiliary write protect. See the Memory
Description section.
2 — — 0 MPEN
Controls main write protect. See the Memory Description
section.
1 — — 0 INV1
Configures buffer 1 with OUT1 = MINT +
(INV1 [XOR] IN1).
0 — — 0 INV2 Configures buffer 2 with OUT2 = INV2 [XOR] IN2.
8A to 8B EEPROM — — Reserved
8C EEPROM R/W A2 Device address
Contains Main Device address if the bit ADFIX = 1. If
ADFIX = 0, then address A2h is used.
8D EEPROM — — Reserved —
8E EEPROM R/W
Contains bits used to perform right shift operations on the
A/D output converter. See the Right Shift A/D Conversion
Result section.
