Notes:
(1)
a discrete pull up resistor is used
(3)
function depends on firmware
(4)
DNU: Do Not Use, Do Not Connect
(5)
GPIO pin. These pins may be programmed as analog-in, i-disconnected, i-float, i-pu, i-pd, o-pp (output push/pull),
o-od (output open drain), o-os (output open source) or some alternate function;
(6)
signal must be accessible for homologation purposes. Refer to 3.9 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 3.3.4 Dynamic I/O Signal Type Changes depending on the UICP status
(9)
for compatibility to BlueMod+SR this pin is reserved for an external antenna and must be left open
