Pull-Up function of 5V tolerant I/O

Please do not input the signal more than VCC voltage at the time of Pull-Up function use of 5V tolerant I/O.

Adjoining wiring on circuit board

If wiring of the crystal oscillation circuit X1A adjoins and also runs in parallel with the wiring of P48/VREGCTL, there is a possibility

that the oscillation erroneously counts because X1A has noise with the change of P48/VREGCTL. Keep as much distance as

possible between both wirings and insert the ground pattern between them in order to avoid this possibility.

Handling when using debug pins

When debug pins(TDO/TMS/TDI/TCK/TRSTX or SWO/SWDIO/SWCLK) are set to GPIO or other peripheral functions, only set

them as output, do not set them as input.
