Figure 11-6 ASC0 Interrupt Generation
As shown in Figure 11-6, S0TBIR is an early trigger for the reload routine, while S0TIR
indicates the completed transmission. Therefore, software using handshake should rely
on S0TIR at the end of a data block to ensure that all data has really been transmitted.
