SCON
Serial Channel Control Register
Field
RI
TI
The serial interface interrupt is generated by a logical OR of flag RI and TI in SFR
SCON. Neither of these flags is cleared by hardware when the service routine is
vectored to. In fact, the service routine will normally have to determine whether it was the
receive interrupt flag or the transmission interrupt flag that generated the interrupt, and
the corresonding bit will have to be cleared by software.
