PTCON — Protect CONFIG Register Bit
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
When cleared, BPRT[3:0] allow programming and erasure of the
associated block.
Table 4-7. EEPROM Block Protect in MC68HC811E2 MCUs
0 = CONFIG register can be programmed or erased normally.
1 = CONFIG register cannot be programmed or erased.
1. x is determined by the value of EE[3:0] in CONFIG register. Refer to
