5 EPLD SOURCE LISTING
Source listing for a ICT
PEEL22CV10AZ epld
. The EPLD functions to generate control signals for the QS3125 quad n-channel switch, to
clamp unused Y lines during scanning, and to control the Y gate dwell time after the rise of an X line. This latter feature allows for moisture
suppression since the charge transfer duration decreases (and thus is less responsive to the slow-moving charges from resistive water films)
with decreasing dwell time. Rt and Ct (R21 and C12 in the E6S3) govern this delay time after the rise of any X line.
