19.5.2
FLMCR2 is a register that displays the state of flash memory programming/erasing.
19.5.3
EBR1 specifies the flash memory erase block. EBR1 is initialized to H'00 when a high level is
input to the FWP pin. It is also initialized to H'00, when the SWE bit in FLMCR1 is 0 regardless
of value in the FWP pin. Do not set more than one bit at a time in EBR1 and EBR2, as this will
cause all the bits in EBR1 and EBR2 to be automatically cleared to 0.

Description
Indicates that an error has occurred during an operation
on flash memory (programming or erasing). When flash
memory goes to the error-protection state, FLER is set to
1.
See section 19.9.3, Error Protection, for details.
Reserved
These bits are always read as 0.
Description
When this bit is set to 1, 4 kbytes of EB7 (H'007000 to
H'007FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB6 (H'006000 to
H'006FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB5 (H'005000 to
H'005FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB4 (H'004000 to
H'004FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB3 (H'003000 to
H'003FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB2 (H'002000 to
H'002FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB1 (H'001000 to
H'001FFF) are to be erased.
When this bit is set to 1, 4 kbytes of EB0 (H'000000 to
H'000FFF) are to be erased.
