Notes:
(1) a discrete pull up resistor is used
(3) function depends on firmware
(4) DNU: Do Not Use, Do Not Connect
(6) signal must be accessible for homologation purposes. Refer to 3.10 Test Mode
(7) signals sampled at startup time. TESTMODE# is I-PU, BOOT0 is I-PD during sampling time only, I-DIS otherwise
(8) Pin Type depends on UICP status. Refer to 3.3.5 Dynamic I/O Signal Type Changes Depending on UICP Status
(9) for compatibility to SR this pin is reserved for an external antenna and must be left open
