MC9S08JM32 SCI question

Hi All,

 

Is the first time I write the SCI code for RS232. The Processor Expert helps a lot, but I can´t understand a very simple question:

 

Why I must activate interrupts for sending and receiving more than one character?

I only can edit the buffer size once I activate the IRQs... why it´s linked?

 

Am I missing something?

 

Cheers.
