2.5.1.2 EPROM and EEPROM Programming Control Register
Data Sheet

Bits [7:5] — Unimplemented
PTCON — Protect CONFIG Register Bit
BPRT[3:0] — Block Protect Bits for EEPROM
The EPROM and EEPROM programming control register (PPROG) selects and
controls the EEPROM programming function. Bits in PPROG enable the
programming voltage, control the latching of data to be programmed, and select
the method of erasure (for example, byte, row, etc.).
Always read 0
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
When cleared, BPRT[3:0] allow programming and erasure of the associated
block.
Address: $1035

Read:
Write:
0 = CONFIG register can be programmed or erased normally.
1 = CONFIG register cannot be programmed or erased.
