The data in this register does not represent the boot voltage
programmed by “BT” pin, which can be read via SET_VID.

SPUP_dBAND_K
For Advanced User ONLY. Speedup (other than Bit[2:0] = Original)
will disable frequency limiter so the switching frequency could
increase with the load repetitive rate. The higher the
capacitance, the faster the speed, which could lead to PSI1/2 to
PS0 transition oscillation. Use with caution.
