Bit 7—Flash Memory Error (FLER): 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.
Bit 6—Reserved: This bit is always read as 0.
Bit 5—Erase Setup Bit 2 (ESU2): Prepares for a transition to erase mode (applicable addresses:
H'20000 to H'3FFFF). Do not set the PSU2, EV2, PV2, E2, or P2 bit at the same time.
Bit 4—Program Setup Bit 2 (PSU2): Prepares for a transition to program mode (applicable
addresses: H'20000 to H'3FFFF). Do not set the ESU2, EV2, PV2, E2, or P2 bit at the same time.
