Hi Friends,
I got few basic question to clarify on microcontrollers (Mc), please help me.
Ex: Take any 16/32 bit Mc
1.In brand new Mc, is there any inbuilt interrupt service routine for UART protcol or we have to write a driver code to handle all the acknowledgment between rs232 & Mc. who all do these stuff i.e we have to write the code or it will be in built ??
Ex: in 8051
Mov r3,#'A'
Mov sbuf,r3
after placing this code for transmission on sbuf, we get an interrupt say that a character has been sent. So my question is who will take care of the interrupt & the service routine. is it inbuilt ??
