Bit 6—Software Write Enable Bit (SWE): Enables or disables flash memory programming.
SWE should be set before setting bits ESU, PSU, EV, PV, E, P, and EB9 to EB0, and should not
be cleared at the same time as these bits.
Bit 5 and 4—Reserved: Read-only bits, always read as 0.
Bit 3—Erase-Verify (EV): Selects erase-verify mode transition or clearing. Do not set the SWE,
ESU, PSU, PV, E, or P bit at the same time.
Bit 2—Program-Verify (PV): Selects program-verify mode transition or clearing. Do not set the
SWE, ESU, PSU, EV, E, or P bit at the same time.
