setting its corresponding register bit, it cannot be unprotected (the register bit cannot be
cleared) without powering down the device.
SPROT7–SPROT0—Sector Protection
Each bit corresponds to a 3 KB Flash sector for Z8F2480 devices. For the Z8F1680
devices each bit corresponds to a 2 KB Flash Sector. For the Z8F0880 devices each bit
corresponds to a 1 KB Flash Sector.
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:
FFREQH—Flash Frequency High Byte
High byte of the 16-bit Flash Frequency value.
Flash programming and erasure is not supported for system clock frequencies below
32 kHz or above 20 MHz. The Flash Frequency High and Low Byte registers must be
loaded with the correct value to ensure proper operation of the device.
