uppermost left figure shows ideal operation waveform. number pulses less than number acceleration/deceleration control pulses, operation performed illustrated figure uppermost right. (1') deceleration operation started when number pulses been reached during acceleration operation. Therefore, acceleration deceleration always mirrored. (2') number pulses less than number acceleration/deceleration control pulses during only acceleration operation, operation stopped pulse rate middle acceleration. (4') number pulses less than number acceleration/deceleration control pulses during only deceleration operation, last pulse rate does reach target value. number pulses output accordance with deceleration pulse curve, operation stopped.

NOTES CMOS DEVICES
PRECAUTION AGAINST SEMICONDUCTORS Note: Strong electric field, when exposed device, cause destruction gate oxide ultimately degrade device operation. Steps must taken stop generation static electricity much possible, quickly dissipate once, when occurred. Environmental control must adequate. When dry, humidifier should used. recommended avoid using insulators that easily build static electricity. Semiconductor devices must stored transported anti-static container, static shielding conductive material. test measurement tools including work bench floor should grounded. operator should grounded using wrist strap. Semiconductor devices must touched with bare hands. Similar precautions need taken boards with semiconductor devices HANDLING UNUSED INPUT PINS CMOS Note: connection CMOS device inputs cause malfunction. connection provided input pins, possible that internal input level generated noise, etc., hence causing malfunction. CMOS devices behave differently than Bipolar NMOS devices. Input levels CMOS devices must fixed high using pull-up pull-down circuitry. Each unused should connected with resistor, considered have possibility being output pin. handling related unused pins must judged device device related specifications governing devices. STATUS BEFORE INITIALIZATION DEVICES Note: Power-on does necessarily define initial status device. Production process does define initial operation status device. Immediately after power source turned devices with reset function have been initialized. Hence, power-on does guarantee out-pin levels, settings contents registers. Device initialized until reset signal received. Reset operation must executed immediately after power-on devices having reset function.
