20.9.8
When oscillation is not stabilized or programmer mode is being set up, no command can be
accepted. Transition to memory-read mode is made after the programmer mode set up time has
elapsed. See section 20.11, AC Characteristics and Timing in Programmer Mode.

programming/erasing. As a high voltage is applied to the flash memory during
programming/erasing, doing so may damage flash memory permanently. If a reset is input
accidentally, the reset must be released after a reset period of 100 μs, which is longer than
usual.
