These conditions can generate CPU interrupt requests from the SCI
transmitter:

•
SCI transmitter empty (SCTE) — The SCTE bit in SCS1 indicates
that the SCDR has transferred a character to the transmit shift
register. SCTE can generate a transmitter CPU interrupt request.
Setting the SCI transmit interrupt enable bit, SCTIE (SCC2),
enables the SCTE bit to generate transmitter CPU interrupt
requests.
Transmission complete (TC) — The TC bit in SCS1 indicates that
the transmit shift register and the SCDR are empty and that no
break or idle character has been generated. The transmission
complete interrupt enable bit, TCIE (SCC2), enables the TC bit to
generate transmitter CPU interrupt requests.
Serial Communications Interface (SCI)
shows the structure of the SCI receiver.
