Hardware Protection: Suspends or disables the programming and erasing of flash memory, and
resets the flash memory control register (FLMCR) and erase block registers (EBR1 and EBR2).
The error-protect function permits the P and E bits to be set, but prevents transitions to program
mode and erase mode. Details of hardware protection are as follows.

Notes: 1. Program-verify, erase-verify, and prewrite-verify modes.
Error Protect: This protection mode is entered if one of the error conditions that set the FLER bit
in RAMCR is detected while flash memory is being programmed or erased (while the P bit or E
bit is set in FLMCR). These conditions can occur if microcontroller operations do not follow the
programming or erasing algorithm. Error protect is a flash-memory state. It does not affect other
microcontroller operations.
In this state the settings of the flash memory control register (FLMCR) and erase block registers
(EBR1 and EBR2) are preserved*, but program mode or erase mode is terminated as soon as the
error is detected. While the FLER bit is set, it is not possible to enter program mode or erase

programming and erasing. To obtain this
protection, V
When a reset occurs (including a
watchdog timer reset) or standby mode is
entered, FLMCR, EBR1, and EBR2 are
initialized, disabling programming and
erasing. Note that RES input does not
ensure a reset unless the RES pin is held
low for at least 20 ms at power-up (to
enable the oscillator to settle), or at least
10 system clock cycles ( ) during
operation.
If an operational error is detected during
programming or erasing of flash memory
(FLER = 1), the FLMCR, EBR1, and EBR2
settings are preserved, but programming
or erasing is aborted immediately. This
type of protection can be cleared only by a
reset or hardware standby.
