Bit 0—Program 1 (P1): Selects program mode transition or clearing (applicable addresses:
H'00000 to H'1FFFFF). Do not set the SWE, PSU1, ESU1, EV1, PV1, or E1 bit at the same time.

FLMCR2 is an 8-bit register used for flash memory operating mode control. Program-verify mode
or erase-verify mode for addresses H'20000 to H'3FFFF is entered by setting SWE (FLMCR1) to
1 when FWE (FLMCR1) = 1, then setting the EV2 or PV2 bit. Program mode for addresses
H'20000 to H'3FFFF is entered by setting SWE (FLMCR1) to 1 when FWE (FLMCR1) = 1, then
setting the PSU2 bit, and finally setting the P2 bit. Erase mode for addresses H'20000 to H'3FFFF
is entered by setting SWE (FLMCR1) to 1 when FWE (FLMCR1) = 1, then setting the ESU2 bit,
and finally setting the E2 bit. FLMCR2 is initialized to H'00 by a reset, in hardware standby mode
and software standby mode, when a low level is input to the FWE pin, and when a high level is
input to the FWE pin and the SWE bit in FLMCR1 is not set (the exception is the FLER bit, which
is initialized only by a reset and in hardware standby mode). When on-chip flash memory is
disabled, a read will return H'00, and writes are invalid.
Writes to bits SWE, ESU2, PSU2, EV2, and PV2 in FLMCR2 are enabled only when FWE
(FLMCR1) = 1 and SWE (FLMCR1) = 1; writes to the E2 bit only when FWE (FLMCR1) = 1,
SWE (FLMCR1) = 1, and ESU2 = 1; and writes to the P2 bit only when FWE (FLMCR1) = 1,
SWE (FLMCR1) = 1, and PSU2 = 1.
