LETF
Fast level detector time constants. 0 = slow level detector time constants are used;
1 = fast level detector time constants are used. See Table 24.
0
ATTB
Attack bound of the MPH and LEV detector. 0 = detectors are unbounded; 1 = range
of the MPH and LEV detector are limited in their range for immediate start of attack. In
AM mode the detectors are always unbounded.
