SCI transmitter empty (SCTE) — The SCTE bit in IRSCS1 indicates that the IRSCDR 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, in IRSCC2 enables the
SCTE bit to generate transmitter CPU interrupt requests.
Transmission complete (TC) — The TC bit in IRSCS1 indicates that the transmit shift register and
the IRSCDR are empty and that no break or idle character has been generated. The transmission
complete interrupt enable bit, TCIE, in IRSCC2 enables the TC bit to generate transmitter CPU
interrupt requests.
