5. Pxy_C and Pxy pins/balls are two separate pads (analog switch open). The analog switch is configured through a SYSCFG
register. Refer to the product reference manual for a detailed description of the switch configuration bits.
6. There is a direct path between Pxy_C and Pxy pins/balls, through an analog switch. Pxy alternate functions are available on
Pxy_C when the analog switch is closed. The analog switch is configured through a SYSCFG register. Refer to the product
reference manual for a detailed description of the switch configuration bits.
7. VREF+ pin, and consequently the internal voltage reference, are not available on the TFBGA100 package. On this package,
this pin is double-bonded to VDDA which can be connected to an external reference. The internal voltage reference buffer is
not available and must be kept disabled
