Bit Bit Name Initial Value R/W Description
2 PV1 0 R/W Program-Verify
When this bit is set to 1, the flash memory transits to
program-verify mode. When it is cleared to 0, program-
verify mode is cancelled.
[Setting condition]
When FWE = 1 and SWE1 = 1
1 E1 0 R/W Erase
When this bit is set to 1 while the SWE1 and ESU1 bits
are 1, the flash memory transits to erase mode. When it
is cleared to 0, erase mode is cancelled.
[Setting condition]
When FWE = 1, SWE1 = 1, and ESU1 = 1
0 P1 0 R/W Program
When this bit is set to 1 while the SWE1 and PSU1 bits
are 1, the flash memory transits to program mode.
When it is cleared to 0, program mode is cancelled.
[Setting condition]
When FWE = 1, SWE1 = 1, and PSU1 = 1
Note: * Set according to the FWE pin state.
17.5.2 Flash Memory Control Register 2 (FLMCR2)
FLMCR2 is a register that displays the state of flash memory programming/erasing. FLMCR2 is a
read-only register, and should not be written to.
Bit Bit Name Initial Value R/W Description
7 FLER 0 R Indicates that an error has occurred during an operation
on flash memory (programming or erasing). When
FLER is set to 1, flash memory goes to the error-
protection state.
See section 17.9.3, Error Protection, for details.
6 to 0 — All 0 — Reserved
These bits are always read as 0.
