Note

Pins P24 through P24_4, P25_0 through P25_7, and P32_0 through P32_6 should not be driven with pull-up drive mode. These pins are used to send signals to the on-board M.2 slot through SMIF, SDIO, and the BT UART Interface. The output of these pins pass through voltage level translators before reaching the M.2 slot. These voltage level translators require a minimum input drive strength of 2mA for the signal to pass through, significantly higher than the 66uA generated when using pull-up drive mode. Strong drive mode is recommended for these pins.
