Bit 2—Program-Verify (PV)*
set the SWE, ESU, PSU, EV, E, or P bit at the same time.)
Bit 2: PV
Description
0
Program-verify mode cleared
1
Transition to program-verify mode
[Setting condition]
When FWE = 1 and SWE = 1

Bit 1—Erase (E)*
*
PSU, EV, PV, or P bit at the same time.)
Bit 1: E
Description
0
Erase mode cleared
1
Transition to erase mode
[Setting condition]
When FWE = 1, SWE = 1, and ESU = 1
Bit 0—Program (P)*
ESU, PSU, EV, PV, or E bit at the same time.)
Bit 0: P
Description
0
Program mode cleared
1
Transition to program mode
[Setting condition]
When FWE = 1, SWE = 1, and PSU = 1
Notes: 1. Do not set multiple bits simultaneously. Do not cut V
2. The SWE bit must not be set or cleared at the same time as other bits (bits EV, PV, E,
and P in FLMCR1, and bits ESU and PSU in FLMCR2).
3. P bit and E bit setting should be carried out in accordance with the program/erase
algorithms shown in section 6.5, Flash Memory Programming/Erasing. Before setting
either of these bits, a watchdog timer setting should be made to prevent program
runaway. See section 6.9, Flash Memory Programming and Erasing Precautions, for
more information on the use of these bits.
