word recognizer for channels 16 through 31. The I/O address 02 (A01U114 pin 12), resets the WR address counter. The
I/O address 03 (A01U114 pin 14) is the clock selecter port. I/O address 02 also controls the glitch trigger shift register,
which enables the glitch trigger circuit.
GLITCH CONTROL (CH 0-7) <21>
This circuit controls only the M218s <21> on the A02 board (data from Pod A). M218’s pin 15 controls the glitch output of
Pin 14. Pin 14 issues a high-level signal if a glitch is captured. By setting pin 15 to high, the output of pin 14 is disabled
(kept low); if pin 15 is low, an output on pin 14 is enabled. Therefore, if a glitch trigger on a certain line is expected, the
corresponding M218’s pin 15 must be low. Since all M218’s pins 14 are wire-ORed, a glitch trigger occurs when any of
