15.8.4 ESCI Status Register 1
ESCI status register 1 (SCS1) contains flags to signal these conditions:
SCTE — ESCI Transmitter Empty Bit
TC — Transmission Complete Bit
SCRF — ESCI Receiver Full Bit
IDLE — Receiver Idle Bit

This clearable, read-only bit is set when the SCDR transfers a character to the transmit shift register.
SCTE can generate an ESCI transmitter CPU interrupt request. When the SCTIE bit in SCC2 is set,
SCTE generates an ESCI 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.
This read-only bit is set when the SCTE bit is set, and no data, preamble, or break character is being
transmitted. TC generates an ESCI transmitter CPU interrupt request if the TCIE bit in SCC2 is also
set. TC is cleared automatically when data, preamble, or break is queued and ready to be sent. There
may be up to 1.5 transmitter clocks of latency between queueing data, preamble, and break and the
transmission actually starting. Reset sets the TC bit.
This clearable, read-only bit is set when the data in the receive shift register transfers to the ESCI data
register. SCRF can generate an ESCI receiver CPU interrupt request. When the SCRIE bit in SCC2 is
set the SCRF generates a CPU interrupt request. In normal operation, clear the SCRF bit by reading
SCS1 with SCRF set and then reading the SCDR. Reset clears SCRF.
This clearable, read-only bit is set when 10 or 11 consecutive logic 1s appear on the receiver input.
IDLE generates an ESCI receiver CPU interrupt request if the ILIE bit in SCC2 is also set. Clear the
IDLE bit by reading SCS1 with IDLE set and then reading the SCDR. After the receiver is enabled, it
