INFO_EN—Information area enable
0 = Information area is not selected
1 = Information area is selected. The information area is mapped into the program
memory 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 Z8F04xx devices, the upper four
bits must always be 0.
The Flash sector protect register is shared with the Flash page select register. When the
Flash control register is locked and written with 5EH, the next write to 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 eight available Flash memory sectors to be protected. The
Reset state of each sector protect bit is zero (unprotected) state. After a sector is protected
by setting its corresponding register bit, the register bit cannot be cleared by you.
SPROT7-SPROT0—Sector protection
Each bit corresponds to a 512-byte Flash sector. For the Z8F04xx devices, all bits are
used.
The Flash frequency high and low byte registers combine to form a 16-bit value, FFREQ,
to control timing for Flash Program and Erase operations. The 16-bit binary Flash
frequency value must contain the system clock frequency (in kHz) and is calculated using
the following equation.
