FLMCR2 is an 8-bit register that monitors the presence or absence of flash memory program/erase
protection (error protection). FLMCR2 is initialized to H'00 by a reset, and in hardware standby
mode.
When on-chip flash memory is disabled, a read will return H'00.
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.

Description
Flash memory is operating normally.
Flash memory program/erase protection (error protection) is disabled.
[Clearing condition]
Power-on reset
An error has occurred during flash memory programming/erasing.
Flash memory program/erase protection (error protection) is enabled.
[Setting condition]
See section 18.8.3, Error Protection.
(Initial value)
Bits 6 to 0⎯Reserved: These bits are always read as 0.
