Description
Flash Write Enable
Reflects the input level at the FWE pin. It is set to 1
when a high level is input to the FWE pin, and
cleared to 0 when a low level is input. When this bit
is cleared to 0, the flash memory transits to the
hardware protection state.
Note: In the H8S/2678R Group, this bit is
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 while FWE = 1 * and SWE
= 1, the flash memory transits 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 while FWE = 1 * and SWE
= 1, the flash memory transits to the program setup
state. When it is cleared to 0, the program setup
state is cancelled.
Erase-Verify
When this bit is set to 1 while FWE = 1 * and SWE
= 1, the flash memory transits to erase-verify
mode. When it is cleared to 0, erase-verify mode is
cancelled.
Program-Verify
When this bit is set to 1 while FWE = 1 * and SWE
= 1, the flash memory transits to program-verify
mode. When it is cleared to 0, program-verify
mode is cancelled.
reserved. This bit is always read as 0 in
modes 1 and 2. This bit is always read as 1
in modes 3 to 7. The initial value should not
be changed.
