−

Not used. Set to logic 0.

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.

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.
