Section 19 ROM
19.23.2 Flash Memory Control Register 2 (FLMCR2)
FLMCR2 is an 8-bit register used for flash memory operating mode control. Program-verify mode
or erase-verify mode for addresses H'040000 to H'07FFFF is entered by setting SWE2 to 1 when
FWE = 1, then setting the EV2 or PV2 bit. Program mode for addresses H'040000 to H'07FFFF is
entered by setting SWE2 to 1 when FWE = 1, then setting the PSU2 bit, and finally setting the P2
bit. Erase mode for addresses H'040000 to H'07FFFF is entered by setting SWE2 to 1 when FWE
= 1, then setting the ESU2 bit, and finally setting the E2 bit. FLMCR2 is initialized to H'00 by a
reset, and in hardware standby mode and software standby mode. When on-chip flash memory is
disabled, a read will return H'00, and writes are invalid.
Writes to the SWE2 bit in FLMCR2 are valid only when FWE = 1;
writes to the ESU2, PSU2, EV2, and PV2 bits only when FWE = 1 and SWE2 = 1;
writes to the E2 bit only when FWE = 1, SWE2 = 1, and ESU2 = 1;
and writes to the P2 bit only when FWE = 1, SWE2 = 1, and PSU2 = 1.
Bit 7—Flash Memory Error (FLER): Indicates that an error has occurred during an operation on
flash memory (programming or erasing). When FLER is set to 1, flash memory goes to the error-
protection state.
