MACRO SERVICE macro service function executed interrupt request carry data operation data transfer hardware terms between special function register area memory space. Upon startup macro service, stops program execution temporarily. 1-byte/2-byte data operation, transfer, etc. automatically carried between special function register (SFR) memory. Upon termination macro service, interrupt request flag reset restarts program execution. When carries macro service operations many into macro service counter (MSC), vectored interrupt request generated after completion. Figure 4-2. Macro Service Processing Sequence Example

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.
