NOTES:
1 _{This pad is configured for Fast (F) pad speed.}
2 _{This pad contains a weak pull-up.}
3 _{This pad contains a weak pull-down.}
NOTE
None of system pins (except RESET) provides an open drain output.
3.4 Pin muxing
Table 3-5 defines the pin list and muxing for this device.
Each entry of Table 3-5 shows all the possible configurations for each pin, via the alternate functions. The
default function assigned to each pin after reset is indicated by ALT0.
NOTE
Pins labeled “NC” are to be left unconnected. Any connection to an external
circuit or voltage may cause unpredictable device behavior or damage.
Pins labeled “Reserved” are to be tied to ground. Not doing so may cause
unpredictable device behavior.
