FLASH-1 Memory
4.8.1 FLASH-1 Block Protect Register
Technical Data
Address:
The block protect register (FLBPR1) is implemented as a byte within the
FLASH-1 memory. Each bit, when programmed, protects a range of
addresses in the FLASH-1 array.
BPR3 — Block Protect Register Bit 3
BPR2 — Block Protect Register Bit 2
