VMID REFERENCE DISCHARGE CONTROL
The VMID reference can be discharged to AGND through internal resistors. Discharging VMID
ensures that a subsequent start-up procedure commences with a known voltage condition; this is
necessary in order to ensure maximum suppression of audible pops associated with start-up. VMID
is discharged by setting VMIDTOG, as described in Table 86.
