12.9.4 SCI Status Register 1
Technical Data

Address:
SCI status register 1 (SCS1) contains flags to signal these conditions:
SCTE — SCI Transmitter Empty Bit

This clearable, read-only bit is set when the SCDR transfers a
character to the transmit shift register. SCTE can generate an SCI
transmitter CPU interrupt request. When the SCTIE bit in SCC2 is set,
SCTE generates an SCI transmitter CPU interrupt request. In normal
operation, clear the SCTE bit by reading SCS1 with SCTE set and
then writing to SCDR. Reset sets the SCTE bit.
