8051 timer calculation Items tagged with 8051 timer calculation

general formula for timer is

(65536-xx)*machine cycle= delay u want
where xx is a 16 bit no having value of TH0 and TL0

when timer run in 16 bit mode with 11.0592 mhz max delay
that can be generated is 72 ms almost.

now let say u use 12MHz crystal then Machine cycle is calculated
as for every crystal value


(crystal value / 12)= frequency

(1 / frequency) = Machine cycle

now for 12 MHz
12... Read Compelte post
