Bit 1 = CPHA Clock Phase.
This bit allows the user to select the phase of the clock output on the SCLK pin. It works in
conjunction with the CPOL bit to produce the desired clock/data relationship (see
and
Bit 0 = LBCL Last bit clock pulse.
This bit allows the user to select whether the clock pulse associated with the last data bit
transmitted (MSB) has to be output on the SCLK pin.
The last bit is the 8th or 9th data bit transmitted depending on the 8 or 9 bit format selected
by the M bit in the SCICR1 register.
Table 76.
These 3 bits (CPOL, CPHA, LBCL) should not be written while the transmitter is enabled.
Data register (SCIDR)
Read/ write
Reset value: Undefined
Contains the received or transmitted data character, depending on whether it is read from or
written to.
The data register performs a double function (read and write) since it is composed of two
registers, one for transmission (TDR) and one for reception (RDR).
The TDR register provides the parallel interface between the internal bus and the output
shift register (see
The RDR register provides the parallel interface between the input shift register and the
internal bus (see
