Flash Sector Protect Register
Description
Sector Protection
For Z8F12xx, Z8F08xx and Z8F04xx devices, all bits are used. For Z8F02xx devices, the
upper four bits remain unused. For Z8F01xx devices, the upper six bits remain unused. To
determine the appropriate Flash memory sector address range and sector number for your
F0830 Series product, please refer to

The Flash Sector Protect Register is shared with the Flash Page Select Register. When the
Flash Control Register is locked and written with
gets the Flash Sector Protect Register. In all other cases, it targets the Flash Page Select
Register.
This register selects one of the eight available Flash memory sectors to be protected. The
Reset state of each sector protect bit is the zero (unprotected) state. After a sector is pro-
tected by setting its corresponding register bit, the register bit cannot be cleared by the
user.
To determine the appropriate Flash memory sector address range and sector number for
your F0830 Series product, please refer to
