#82388 - not has to, but can Responding to: ???'s previous message |
serial interrupt has to be called by setting TI
This is NOT a mandatory method. You can achieve the same result by starting the transmission by SBUF = xxx. The 'set TI to start the transmission' is just a way to use the ISR as startup code as well, do not let it confuse you. In setups where the main set TI it is set once to start the transmission, not for every byte. I get the impresion you are reading through some examples (e.g. the tutorials here) without having the background for understanding them, lay them aside and read the relevant chapters in "the bible", then go back to the tutorials. Erik here are the links to "the bible" Chapter 1 http://www.semiconductors.philips.com/acrobat/v...ARCH_1.pdf chapter 2 http://www.semiconductors.philips.com/acrobat/v...UIDE_1.pdf chapter 3 http://www.semiconductors.philips.com/acrobat/v...WARE_1.pdf |
