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?
