Over-current warning detect adjustment bypass
Table 26.
The OCWARN input is used to indicate an over-current warning condition. When OCWARN
is asserted (set to 0), the power control block forces an adjustment to the modulation limit
(default is -3 dB) in an attempt to eliminate the over-current warning condition. Once the
over-current warning volume adjustment is applied, it remains in this state until reset is
applied. The level of adjustment can be changed via the TWOCL (thermal warning/over
current limit) setting which is address 0x37 of the user defined coefficient RAM.

Compensating Pulse Size
When OM[1,0] = 11, this register determines the
size of the DDX compensating pulse from 0 clock
ticks to 15 clock periods.
