Note:
Bit 7 — Factory use only
Warning: This bit is strictly for factory use only and will always read zero to avoid accidental
EPP — EPROM protect
This bit protects the contents of the main EPROM against accidental modification; it has no effect
on reading or executing code in the EPROM.
RTIM — Reset time
This bit can modify t
This feature is handled in the ROM part via a mask option.
RWAT — Watchdog after reset
This bit can modify the status of the watchdog counter after reset.
WWAT — Watchdog during WAIT mode
This bit can modify the status of the watchdog counter during WAIT mode.
