Notes

Pin 41 is the exposed thermal/ground pad on the bottom of the QFN package.
Multiple pins share the same power supply nets (AVDD10, AVDD33, DVDD0, DVDD33, DVDD_RG); all must be properly decoupled.
Pins 22–27 have alternate functions for configuration and delay control; function selection depends on hardware configuration and strapping.
Pins 32–34 (LED0–LED2) have alternate configuration functions (CFG_EXT, CFG_LDO0, CFG_LDO1).
Pin 31 (INTB/PMEB) is open-drain and requires external pull-up.
PHYRSTB (pin 12) is active-low and must be held low during power-up sequencing.
