USER’S MANUAL
RXDA and RXDB are the serial data inputs to the SCIA and SCIB interfaces, respec-
tively. Each pin is also available as a general-purpose I/O pin when the RE bit in
SCCR1 of the associated SCI submodule is cleared. When used for general-purpose
I/O, RXDA and RXDB may be configured either as input or output as determined by
the RXDA and RXDB bits in the MDDR.
When used for general-purpose I/O, TXDA and TXDB can be configured either as in-
put or output as determined by the TXDA and TXDB bits in the MDDR. The TXDA and
TXDB pins are enabled for SCI use by setting the TE bit in SCCR1 of each SCI inter-
face.
SCI operation can be polled by means of status flags in the SCSR, or interrupt-driven
operation can be employed by means of the interrupt-enable bits in SCCR1.
Data can be transmitted and received in a number of formats. The following terms con-
cerning data format are used in this section:
• Bit-Time — The time required to transmit or receive one bit of data, which is equal
• Start Bit — One bit-time of logic zero that indicates the beginning of a data frame.
• Stop Bit — One bit-time of logic one that indicates the end of a data frame.
• Frame — A complete unit of serial information. The SCI can use 10-bit or 11-bit
• Data Frame — A start bit, a specified number of data or information bits, and at
• Idle Frame — A frame that consists of consecutive ones. An idle frame has no
• Break Frame — A frame that consists of consecutive zeros. A break frame has
to one cycle of the baud frequency.
A start bit must begin with a one-to-zero transition and be preceded by at least
three receive time samples of logic one.
