SCI Control
Register 3
R8 — Received Bit 8
When the SCI is receiving 9-bit characters, R8 is the read-only ninth bit
(bit 8) of the received character. R8 is received at the same time that the
SCDR receives the other 8 bits.
When the SCI is receiving 8-bit characters, R8 is a copy of the eighth bit
(bit 7).
T8 — Transmitted Bit 8
When the SCI is transmitting 9-bit characters, T8 is the read/write ninth bit
(bit 8) of the transmitted character. T8 is loaded into the transmit shift
register at the same time that the SCDR is loaded into the transmit shift
register. Reset has no effect on the T8 bit.
DMARE — DMA Receive Enable Bit
This bit should always remain as logic 0.
DMATE — DMA Transfer Enable Bit
This bit should always remain as logic 0.
ORIE — Receiver Overrun Interrupt Enable Bit
1 = SCI error CPU interrupt requests from OR bit enabled
NEIE — Receiver Noise Error Interrupt Enable Bit
1 = SCI error CPU interrupt requests from NE bit enabled
FEIE — Receiver Framing Error Interrupt Enable Bit
1 = SCI error CPU interrupt requests from FE bit enabled
PEIE — Receiver Parity Error Interrupt Enable Bit
1 = SCI error CPU interrupt requests from PE bit enabled
SCI Status
Register 1
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
