FLASH-1 Memory
Technical Data
BPR2 — Block Protect Register Bit 2
BPR1 — Block Protect Register Bit 1
BPR0 — Block Protect Register Bit 0
By programming the block protect bits, a portion of the memory will be
locked so that no further erase or program operations may be
performed. Programming more than one bit at a time is redundant. If
both bit 1 and bit 2 are set, for instance, the address range
$1000–$FFFF is locked. If all bits are erased, then all of the memory is
available for erase and program. The presence of a voltage V
IRQ pin will bypass the block protection so that all of the memory,
including the block protect register, is open for program and erase
operations.
This bit protects the FLASH memory contents in the address range
$2000–$7FFF.
This bit protects the FLASH memory contents in the address range
$1000–$7FFF.
This bit protects the FLASH memory contents in the address range
$0450–$7FFF.
