Page Control
PAGE_CTRL_0 (0x000)
Field
Slice
Description
REVERT
7:7
0: PAGE maintains its value until re-written
1: PAGE reverts to 0 after one access
WRITE_MODE
6:6
Behavior upon sequential write accesses over the 2-wire
interface
0: Write data to consecutive addresses
1: Write data to arbitrary addresses using address-data pairs
