INFO_EN—Information Area Enable
0 = Information Area us not selected.
1 = Information Area is selected. The Information Area is mapped into the Program Mem-
ory address space at addresses FE00H through FFFFH.
PAGE—Page Select
This 7-bit field identifies the Flash memory page for Page Erase and page unlocking.
Program Memory Address[15:9] = PAGE[6:0]. For the Z8F08xx devices, the upper 3 bits
must be zero. For the Z8F04xx devices, the upper 4 bits must be zero. For Z8F02xx
devices, the upper 5 bits must always be 0. For the Z8F01xx devices, the upper 6 bits must
always be 0.
The Flash Sector Protect (FPROT) register is shared with the Flash Page Select Register.
When the
this address targets the Flash Sector Protect Register. In all other cases, it targets the Flash
Page Select Register.
This register selects one of the 8 available Flash memory sectors to be protected. The reset
state of each Sector Protect bit is an unprotected state. After a sector is protected by setting
its corresponding register bit, it cannot be unprotected (the register bit cannot be cleared)
without powering down the device.
