Mode pins (MD0, MD1)
Connect the MD pin (MD0, MD1) directly to VCC or VSS pins. Design the printed circuit board such that the pull-
up/down resistance stays low, as well as the distance between the mode pins and VCC pins or VSS pins is as
short as possible and the connection impedance is low, when the pins are pulled-up/down such as for switching
the pin level and rewriting the Flash memory data. It is because of preventing the device erroneously switching
to test mode due to noise.
Notes on power-on
To ensure that the internal regulator and the oscillator have stabilized immediately after the power is turned
on, keep an “L” level input connected to the INIT pin for the duration of the regulator voltage stabilization wait
time + the oscillator start time of the oscillator + the main oscillator stabilization wait time.
Turn power on/off in the following order
Turning on : VCC
AVCC AVRH
Turning off : AVRH
AVCC VCC
Release the reset (INIT pin “L” level to “H” level) after the power supply has stabilized.
Caution on operations during PLL clock mode
On this microcontroller, if in case the crystal oscillator breaks off or an external reference clock input stops while
the PLL clock mode is selected, a self-oscillator circuit contained in the PLL may continue its operation at its
self-running frequency.
However, Fujitsu will not guarantee results of operations if such failure occurs.
