/\oo/\ Various reference guides mention that Timer A in the 68901 is available for user applications, and is thus left alone by the system. Great, just what I need. For the life of me, I cannot find any references stating the rate at which the timer clocks. There is a 2.??MHz Xtal and a 4MHz clock input to the device. I was told that an application can use a 1 mS timer but this doesn't seem to be of much use to me, since I need to resolve down towards microsecond precision. Anyone out there in netland know the answer. -- E-Mail (UUCP) AGray@axion.bt.co.uk ...!ukc!axion!AGray Organisation British Telecom Research Laboratories (RT3134) Snail Mail BTRL, Rm G23 B68, Martlesham Heath, IPSWICH IP5 7RE, UK Telephone +44 473 646647
