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.
