This bit is always read as 0.
Software Write Enable
When this bit is set to 1, flash memory
programming/erasing is enabled. When this bit is
cleared to 0, other FLMCR1 register bits and all EBR1
bits cannot be set.
Erase Setup
When this bit is set to 1, the flash memory changes to
the erase setup state. When it is cleared to 0, the
erase setup state is cancelled. Set this bit to 1 before
setting the E bit to 1 in FLMCR1.
Program Setup
When this bit is set to 1, the flash memory changes to
the program setup state. When it is cleared to 0, the
program setup state is cancelled. Set this bit to 1
before setting the P bit in FLMCR1.
