Hi,
I'm learning serial transmission using 8051.i'm using timer 1 in mode2,(commonly used).the timer reloads to (-3) every time it goes to 0 from ffh.the data sent to sbuf is transmitted readily.but when does each bit get transffered?is it when the TF1 is set each time?
in timers,in any mode,if the timer rolls from ffffh to 0,the TF is set,if the tr is not reset will the timer continue to run from 0 again?
in timer mode2 will the TF be set after the first cycle till the timer is off?
