Fast-comparison DAC threshold adjust for high transmit power. This value is added to the APC_DAC value recalled from Table 04h.
If the sum is greater than 0xFF, 0xFF is used. Comparisons greater than APC_DAC plus this value, found on the BMD pin, will
create a TXP-HI alarm.

Fast-comparison DAC threshold adjust for low transmit power. This value is subtracted from the APC_DAC value recalled from
Table 04h. If the difference is less than 0x00, 0x00 is used. Comparisons less than APC_DAC minus this value, found on the BMD
pin, create a TXP-LO alarm.

This value defines the maximum DAC value allowed for the upper 8 bits of IBIAS output during all operations. During the intial step and
binary search, this value will not cause an alarm but will still clamp the IBIAS DAC output. After the startup seqence (or normal APC
operations), if the APC loop tries to create an IBIAS value greater than this setting, it is clamped and creates a BIAS MAX alarm. Settings
00h through FEh are intended for normal APC mode of operation. Setting FFh is reserved for manual IBIAS mode.
