Bits [7:5] — Unimplemented
Always read 0
PTCON — Protect CONFIG Register Bit
0 = CONFIG register can be programmed or erased normally.
1 = CONFIG register cannot be programmed or erased.
BPRT[3:0] — Block Protect Bits for EEPROM
When set, these bits protect a block of EEPROM from being programmed or electronically erased.
Ultraviolet light, however, can erase the entire EEPROM contents regardless of BPRT[3:0] (windowed
packages only). Refer to
Table 2-6
When cleared, BPRT[3:0] allow programming and erasure of the associated block.
