ELSI
Receive pin (SIN) status interrupt enable
bit.
Set by the user to enable generation of
an interrupt if any of the COMSTA0[3:1]
register bits are set.
Cleared by the user.

ETBEI
Enable transmit buffer empty interrupt.
Set by the user to enable an interrupt
when the buffer is empty during a
transmission, that is, when COMSTA[5]
is set.
Cleared by the user.
0
ERBFI
Enable receive buffer full interrupt.
Set by the user to enable an interrupt
when the buffer is full during a
reception.
Cleared by the user.
UART Interrupt Identification Register 0
This 8-bit register reflects the source of the UART interrupt.
