FLER

Flash Memory Error

Indicates that an error has occurred during programming

or erasing the flash memory. When this bit is set to 1,

the flash memory enters the error protection state.

When this bit is set to 1, high voltage is applied to the

internal flash memory. To reduce the damage to the

flash memory, the reset must be released after the reset

input period (period of

RES = 0) of at least 100 µs.

0: Flash memory operates normally (Error protection is

invalid)

[Clearing condition]

• At a reset

1: An error occurs during programming/erasing flash

memory (Error protection is valid)

[Setting conditions]

• When an interrupt, such as NMI, occurs during

programming/erasure.

• When the flash memory is read during

programming/erasure (including a vector read and

an instruction fetch).

• When the SLEEP instruction is executed during

programming/erasure (including software standby

mode).

• When a bus master other than the CPU, such as the

DMAC and DTC, obtains bus mastership during

programming/erasure.
