Used as a positive voltage reference by ADC & DAC. VREFH should be connected
externally to filtered VA.
When this pin goes “H”, soft mute cycle is initiated.
When returning “L”, the output mute releases.
This pin must be connected to DGND.
“H”: Master mode, “L”: Slave mode
“H”: 384fs, “L”: 256fs, “NC”: 512fs
