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.
Fault detect recovery constant registers (addr 0x2B, 0x2C)
FDRC bits specify the 16-bit fault detect recovery time delay. When status register bit FAULT
is asserted, the tristate output is immediately asserted low and held low for the time period
specified by this constant. A value of 0x0001 in this register is approximately 0.083 ms. The
default value of 0x000C gives approximately 0.1 ms.
0x0000 is a reserved value for this register pair. This value must not be used.
Device status register (addr 0x2D)
This read-only register provides the fault, warning and PLL status from the power control
block.
