MPCC bits determine the 16 MSBs of the MPC compensation coefficient. This coefficient is

used in place of the default coefficient when MPCV = 1.

5.11

Variable distortion compensation registers (addr 0x29 -

0x2A)

DCC bits determine the 16 MSBs of the Distortion compensation coefficient. This coefficient

is used in place of the default coefficient when DCCV = 1.

5.12

Fault detect recovery constant registers (addr 0x2B - 0x2C)

FDRC bits specify the 16-bit fault detect recovery time delay. When FAULT is asserted, the

TRISTATE output is immediately asserted low and held low for the time period specified by

this constant. A constant value of 0x0001 in this register is approximately 0.083 ms. The

default value of 0x000C gives approximately 0.1 ms.

5.13

Device status register (addr 0x2D)

This read-only register provides fault and thermal-warning status information from the power

control block. Logic value 1 for faults or warning means normal state. Logic 0 means a fault

or warning detected on power bridge. The PLLUL = 1 means that the PLL is not locked.
