C2 SCLSYS D/I Serial interface clock input for system access. Connect a pull-up resistor. Serial bus address selection. Connect to GND (addr = 60h), VIOSYS (addr = 61h), SDASYS C4 ADDR D/I (addr = 62h) or SCLSYS (addr = 63h). Full Power to Low Power state transition control signal (By default active LOW for Low-Power C6 NSLP D/I PFM mode) Internal supply voltage capacitor pin. A ceramic low ESR 1-µF capacitor should be connected C7 VLDO A from this pin to GNDA. The LDO voltage is generated internally, do NOT supply or load this pin externally. D1 FBB5 A Not used for six-phase converter. Connect to GND. D2 FBB3 −/B4 A Not used for six-phase converter. Connect to GND. D3 FBB3+/B3 A Not used for six-phase converter. Connect to GND.
