Table 10. Pin description
(*) is not available in this version.
(**) To allow for design flexibility and support for multiple sensors with different voltages,
the VDDIO banks are split, such that some of the VDDIO banks can be 1.8 V and some can
be 3.3 V. If a VDDIO bank is connected to 1.8 V then the corresponding I/O signals for that
bank should be driven at the same voltage.
VDDIO Bank 1 : GPIO28~29, JTAG,
VDDIO Bank 2 : SPI1(Master), Misc
VDDIO Bank 3 : GPIO18~23, PWM
VDDIO Bank 4 : I2C, SPI2(Slave), GPIO16~17
VDDIO Bank 5 : UART0~1
VDDIO Bank 6 : GPIO30~31
