Power Supplies:
Power-Up (PDN pin = “H”, PD0 bit=“0”)
Power-Down (PDN pin = “L”, PD0 bit = “0”)
Note 23. PLL Master Mode (MCKI=12.288MHz) and PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR =
Note 24. PMADL = PMADR = PMDAC = PMLO = PMHPL = PMHPR = PMVCM = PMPLL = PMMIN bits = “1”.
Note 25. All digital input pins are fixed to each supply pin (TVDD1, TVDD2 or TSVDD) or (VSS2 or VSS3).
