 		 #117814 - AT89S8252 MIDI Baud Rate
Responding to: ???'s previous message
Dimitri,

No the timer is in auto-reload. Also as Erik pointed out for your purposes the priority/interrupt bits are not in effect in this mode so are not needed (i just rough cut from some source).

But since you are using interrupt processing you will need to set the Priority appropriatly using the "PS" bit in the "IP" and enable the interrupt using the "ES" bit in the IE Register.

regards,
p
