8.11 Variable Max Power Correction (Address 27h-28h):
MPCC bits determine the 16 MSBs of the MPC compensation coefficient. This coefficient is used in place
of the default coefficient when MPCV = 1.
Table 35.
8.12 Fault Detect Recovery (Address 2Bh-2Ch):
FDRC bits specify the 16-bit Fault Detect Recovery time delay. When FAULT is asserted, the TRISTATE
output will be immediately asserted low and held low for the time period specified by this constant. A con-
stant value of 0001h in this register is ~.083ms. The default value of 000C specifies ~.1mSec.
