This register specifies the prescaler value for a given system clock required to generate the
correct timing for Flash write/erase operations. If the prescaler is set to 1111b, Flash
write/erase operations are disabled.

1111: Flash Memory Write/Erase Disabled
The prescaler value is the smallest value satisfying the following equation:
FLASCL > log
* For test purposes. The C8051F018/9 is not guaranteed for operation over 25MHz.
