EXTS0–1
Output
Digitized Output bits
—These are the gray-scale encoded digitized
representation of ADIN. The transition levels are relative to the
measured peak and valley signal levels.
EXTS0 = 1, EXTS1 = 0: 5/ 6 < ADIN < 1
EXTS0 = 1, EXTS1 = 1: 1/ 2 < ADIN < 5/ 6
EXTS0 = 0, EXTS1 = 1: 1/ 6 < ADIN < 1/ 2
EXTS0 = 0, EXTS1 = 0: 0 < ADIN < 1/ 6

CON0–1
Input
Mode Configuration
—CON0 and CON1 specify the mode of operation for the
MC68176.
CON0 = 0, CON1 = 0: Lower Power Standby mode
CON0 = 0, CON1 = 1: Fast Track mode
CON0 = 1, CON1 = 0: Hold mode
CON0 = 1, CON1 = 1: Slow Track mode
Track Inhibit
—This signal controls the operation of the peak and valley audio
signal strength detectors. TRKINH is synchronized with the falling edge of
CLOCK.
TRKINH
Input
TRKINH = 0: Enables peak and valley counters and enables decay.
TRKINH = 1: Disables peak and valley counters and disables decay.
