Description
0x0: mirror roll-off frequency control = bypass.
0x1: mirror roll-off frequency control = narrowest bandwidth.
0x2: mirror roll-off frequency control = medium bandwidth.
0x3: mirror roll-off frequency control = widest bandwidth.
See the plot in the Analog Control Registers section.
0xCA: output stack headroom control.
HDRM[7:4]: set the reference offset from AVDD33 (VCAS centering).
HDRM[3:0]: set the overdrive (current density) trim (temperature tracking).
Description
0x0: if the correct value is not found, the search stops.
0x1: if the correct value is not found, the search begins again.
0x0: not exact (can find a phase within two values of the desired phase).
0x1: finds the exact phase that is targeted (optimal setting).
0x0: mu controller has not lost lock.
0x1: mu controller has lost lock.
0x0: mu controller is not locked.
0x1: mu controller is locked.
