Section 19 ROM (Preliminary)
high level is input to the FWE pin, and H'00 when a low level is input. When on-chip flash
memory is disabled, a read will return H'00, and writes are invalid.
Writes are enabled only in the following cases: Writes to bit SWE1 of FLMCR1 enabled when
FWE = 1, to bits ESU1, PSU1, EV1, and PV1 when FWE = 1 and SWE1 = 1, to bit E1 when
FWE = 1, SWE1 = 1 and ESU1 = 1, and to bit P1 when FWE = 1, SWE1 = 1, and PSU1 = 1.
Note:
Bit 7—Flash Write Enable Bit (FWE): Sets hardware protection against flash memory
programming/erasing.

Bit 6—Software Write Enable Bit 1 (SWE1): This bit selects write and erase valid/invalid of the
flash memory. Set it when setting bits 5 to 0, bits 7 to 0 of EBR1, and bits 3 to 0 of EBR2.
