Description
Reflects the input level at the FWE pin. It is set to 1
when a low level is input to the FWE pin, and
cleared to 0 when a high level is input.
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 and EBR2 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.
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 P1 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.
Program-Verify
When this bit is set to 1, the flash memory changes
to program-verify mode. When it is cleared to 0,
program-verify mode is cancelled.
Erase
When this bit is set to 1 while the SWE1 and ESU1
bits are 1, the flash memory changes to erase
mode. When it is cleared to 0, erase mode is
cancelled.
Program
When this bit is set to 1 while the SWE1 and PSU1
bits are 1, the flash memory changes to program
mode. When it is cleared to 0, program mode is
cancelled.
