6. Procedure to Calculate the Delay Program SET the TMOD register For example, if we want to operate timer1 in mode1 it must be configured as “TMOD=0x10”. CALCULATE TH1 & TL1 E xample: 500us time delay 500us/1.080806us 461pulses P=65535-461 P=65074 65074 converted by hexadecimal =FE32 TH1=0xFE; TL1=0x32; Start the timer1 “TR1=1;” Monitor the flag bit “while(TF1==1)” Clear the flag bit “TF1=0” Cleat the timer “TR1=0”
