26.3.2.1 Flash Clock Divider Register (FCLKDIV)
The FCLKDIV register is used to control timed events in program and erase algorithms.
All bits in the FCLKDIV register are readable, bit 7 is not writable, bit 6 is write-once-hi and controls the
writability of the FDIV field in normal mode. In special mode, bits 6-0 are writable any number of times
but bit 7 remains unwritable.
