= PMPCMB bits = “1”. PLL Reference Clock = MCKI = 11.2896MHz. In this case, output current of the
MPWR1 and MPWR2 pins are 0mA.
AVDD= 4.6mA (typ), DVDD= 4.0mA (typ), PVDD= 0.78mA (typ), SVDD=4.2mA (typ), TVDD = 0.2mA (typ)
Note 34. All digital input pins are fixed to each supply pin TVDDA, TVDDE or VSS2, VSS4.
Note 35. AVDD, DVDD, PVDD, TVDDA, VDDE and TVDDE are powered OFF.
Note 36. fs=8 kHz 16 bit (FSD bits=0h, LAW bits = 0h, DIFD bit = 3h, TESTC bits = 1h, DSP running with programmed
connecting DIN1 with DOUT2 and DIN2 with DOUT1.
