Reserved
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.
Erase-Verify
When this bit is set to 1, the flash memory changes to
erase-verify mode. When it is cleared to 0, erase-verify
mode is cancelled.
