CAUTION:
CAUTION:
R8 — Received Bit 8
T8 — Transmitted Bit 8
DMARE — DMA Receive Enable Bit
The DMA module is not included on this MCU. Writing a logic 1 to
DMARE or DMATE may adversely affect MCU performance.
DMATE — DMA Transfer Enable Bit
The DMA module is not included on this MCU. Writing a logic 1 to
DMARE or DMATE may adversely affect MCU performance.
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). Reset has no effect on the R8 bit.
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.
1 = DMA not enabled to service SCI receiver DMA service requests
0 = DMA not enabled to service SCI receiver DMA service requests
1 = SCTE DMA service requests enabled; SCTE CPU interrupt
0 = SCTE DMA service requests disabled; SCTE CPU interrupt
