Section 6 ROM
6.6.2
FLMCR2 is a register that displays the state of flash memory programming/erasing. FLMCR2 is a
read-only register, and should not be written to.
Bit 7—Flash Memory Error (FLER)
This bit is set when the flash memory detects an error and goes to the error-protection state during
programming or erasing to the flash memory. See section 6.9.3, Error Protection, for details.
Bit 7
FLER
0
1
Bits 6 to 0—Reserved
These bits are always read as 0 and cannot be modified.
6.6.3
EBR specifies the flash memory erase area block. EBR is initialized to H'00 when the SWE bit in
FLMCR1 is 0. Do not set more than one bit at a time, as this will cause all the bits in EBR to be
automatically cleared to 0. When each bit is set to 1 in EBR, the corresponding block can be
erased. Other blocks change to the erase-protection state. See table 6.7 for the method of dividing
blocks of the flash memory. When the whole bits are to be erased, erase them in turn in unit of a
block.
