Pinout and signal descriptions
1 Reset configuration is given as I/O direction and pull direction (for example, “Input, pullup”).
2 Although this signal is not a supply for RSDS pads, it needs to be terminated in an external capacitor with a value of 47 pF.
3 VREG_BYPASS should be pulled down externally.
2.4.5 Nexus pins
On the 176 LQFP and the 208 LQFP package options a reduced set of Nexus pins are optionally available, multiplexed with
GPIO pins.
On the 416 TEPBGA package option all Nexus pins are dedicated to Nexus only.
