149.0. "more on RTC address" by TRN01::FORMIA () Mon Jan 16 1995 11:55

    thanks a lot,
    I explain the reason.....
    
   	I'm trying to use an existing driver for rtc of VMEAX-300 written by 
    IRTV for a DEC project and seems that the rtc structure is the same 
    to KAV-30 but the address has to be different.                                                  
	Moreover I must start a routine every 4.88 msec that is not simple
    with KAV$RTC.
     
    thanks for your help

149.1why RTC - timers might be easier...EICMFG::KAV30_SUPPTue Jan 17 1995 10:0814
    Hi Marino,
    
    if you need to have some time signal at predefined intervalls, why
    don't you use the KAV$timer calls ? These run with a 'tick' of 400nsec,
    so it should be easy to create an intervall of 4.88 msec - the examples
    coming with ELN show how to use the timers.
    
    I will also look into the differences of VMEAX300 and KAV30 to tell you
    wether it's easy to use the IRTV driver on KAV30 or not...
    
    best regards,
    
    	Thomas
