0068 * 0069 * PARAMETER INPUT: 0070 * NOM NS Q: XXXX 400 TO 1600 NANOSECOND NOMINAL CPU TIME 0071 * (775, 960, OR 1600 DEFAULT) 0072 * FREQ Q: XXXX 50 TO 1000 HZ (60 DEFAULT) 0073 * SAMPLE Q: XXXX 1 TO 1000 CLOCK CYCLES (600 DEFAULT) 0074 * HOUR Q: XX 0 TO 23 INITIAL VALUES FDR TIME-OF-DAY 0075 * MINUTE Q: XX 0 10 59 CLOCK (00:00 DEFAULT) 0076 * 0077 * THE INPUT MAY BE TERMINATED WITH A CR OR 0078 * A PERIOD. THE TERMINATOR ALONE WILL USE THE 0079 * DEFAULT OR PREVIUUS VALUE. ANY UNACCEPTABLE 0080 * VALUE WILL CAUSE THE REQUEST FOR BOTH 0081 * PARAMETERS TO BE REPEATED. VALID PARAMETERS 0082 * ARE ACKNOWLEDGED WITH A CR/LF. 0083 * THE PARAMETERS MUST BE CHOSEN SUCH THAT 1000 TIMES 0084 * THE SAMPLE DIVIDED BY THE FREQUENCY IS LESS THAN 0085 * 16768. THE MEASURED RESULT MUST ALSO BE UNDER 16768 0086 * TO AVOID 'RI' AND 'DZ' ERRORS. 0087 * 0088 * TIMING CPU CLOCK TIME: 0089 * USE THE SWEEP SECOND HAND OF A CLOCK OR WATCH AND NOTE THE 0090 * TIME THE C/R OR PERIOD IS GIVEN AT THE END OF THE NOMINAL 0091 * NANOSECOND INPUT. ON THE ONE MINUTE MARK HIT THE START 0092 * BUTTON TO CAUSE AN INTERRUPT. WITH A LITTLE PRACTICE THE 0093 * RESULT SHOULD BE CONSISTANT AND ACCURATE TO 0.3 %. 0094 * 0095 * 0096 * OUTPUT DATA - CPU OPERATION TIME 0097 * 0098 * THE OUTPUT MESSAGE GIVES THE TIME IN NANOSECONDS OF ONE 0099 * GENERIC NO OPERATION AND THE PERCENT DEVIATION FROM THE 0100 * NOMINAL TIME. DEPENDING UPON THE MEMORY TYPE THE TIME MAY 0101 * BE ONE CYCLE OF THE MEMORY OR ONE CYCLE OF THE CPU. 0102 * 0103 * TO CALIBRATE A 'SCOPE START THE PROCESS, BUT DO NOT PUSH 0104 * THE START BUTTON. THE LOOP WILL RUN FOREVER. 0105 * 0106 * 0107 * 0108 * 0109 * OUTPUT DATA - ERRORS 0110 * 0111 * ON DETECTION OF CERTAIN ANTICIPATED ERRORS, AN 0112 * ERROR MESSAGE WILL BE SENT TO THE ASR WHICH WILL 0113 * INDICATE THE ERROR THAT HAS OCCURRED. 0114 * 0115 * ER1 - INTERRUPT NOT RTC 0116 * 0117 * ER3 - INTERRUPT NOT RESET
