Description

PV1

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

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

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.
