I use Keil sometimes and while using a timer in autoload mode, the TH0 is loaded with the calculated value but TL0 starts incrementing from 00 instead of the calculated value F0.Am I missing something while using or configuring the keil simulator?
I have not invited comments on my copy paste abilities , but wamt solns from the experts in this forum. you can hardly expect 'solons' when posting incorrect 'code'
void delay() { TMOD = 0x02; TH0 = 0xF0; TL0 = 0xF0; TRO = 1 while(TF0==0) // corrected by information from last post TR0 = 0; TF0 = 0; }
why do you use reload mode?
Erik
"why do you use reload mode?"
but that's 2ndary to his question: aka the code would behave the same regardless if a reload mode is used or not.
not necessarily, reload mode is an 8bit counter other modes are 13/16 bit
"not necessarily, reload mode is an 8bit counter other modes are 13/16 bit"
since you have trouble understanding it, please allow me to restate it:
THE code would behave the same regardless if a reload mode is used or not.
I did not say that ANY code would behave the same regardless if a reload mode is used or not.
hope it help with your comprehension of what I wrote.
THE code would behave the same regardless if a reload mode is used or not. it seems that it mis you that have "trouble understanding it"
TH0 = 0xF0; TL0 = 0xF0;
in reload mode (8 bit) would count up from 0xF0 to 0 (expressed as 16 bit: 0xFFF0 to 0) in other (16bit) modes wold count up from 0xF0F0 to 0 - a whole lot longer!
