USER REGISTER MAP

Figure 10 provides a diagram of the dual memory structure

used to manage operation and store user settings. Writing con-

figuration data to a control register updates its SRAM contents,

which are volatile.

Most of the user registers have mirror locations in flash memory

(see Table 8, for “yes” in the Flash Backup column). Use the

manual flash backup command in GLOB_CMD[6] (DIN =

0xBE40) to save these settings into the nonvolatile flash memory.

The flash backup process requires a valid power supply level and

zero SPI communication for the entire 28 ms process time.
