3.14.1.5
SPI Data Register – SPDR
The SPI Data Register is a read/write register used for data transfer between the Register File
and the SPI Shift Register. Writing to the register initiates data transmission. Reading the regis-
ter causes the Shift Register Receive buffer to be read.
3.14.2
Data Modes
There are four combinations of SCK phase and polarity with respect to serial data, which are
determined by control bits CPHA and CPOL. The SPI data transfer formats are shown in Figure
3-54 and Figure 3-55 on page 118. Data bits are shifted out and latched in on opposite edges of
the SCK signal, ensuring sufficient time for data signals to stabilize. This is clearly seen by sum-
Figure 3-54. SPI Transfer Format with CPHA = 0
