11.5
Four bit-addressable interrupt control registers are provided for serial channel ASC0.
Register S0TIC controls the transmit interrupt, S0TBIC controls the transmit buffer
interrupt, S0RIC controls the receive interrupt, and S0EIC controls the error interrupt of
serial channel ASC0. Each interrupt source also has its own dedicated interrupt vector.
S0TINT is the transmit interrupt vector, S0TBINT is the transmit buffer interrupt vector,
S0RINT is the receive interrupt vector, and S0EINT is the error interrupt vector.
The cause of an error interrupt request (framing, parity, overrun error) can be identified
by the error status flags in control register S0CON.
Note: In contrast to the error interrupt request flag S0EIR, the error status flags S0FE/

S0PE/S0OE are not reset automatically upon entry into the error interrupt service
routine, but must be cleared by software.
