CHAPTER 14 UART, SERIAL I/O INTERFACE (SIO), INPUT CAPTURE MODULE, AND OUTPUT COMPARE

■ Interrupt Function

The serial I/O interface can generate an interrupt request for the CPU. An interrupt request is outputted to

the CPU when both the serial I/O interrupt request (SIR) bit (i.e., interrupt flag) and the serial I/O interrupt

enable (SIE) bit of the SMCS register are "1" at the end of data transfer. Figure 14.2-9 shows the timing of

interrupt signal output.
