SPI Data Register
7
The SPI Data Register stores both the outgoing (transmit) data and the incoming (receive)
data. Reads from the SPI Data Register always return the current contents of the 8-bit
Shift Register. Data is shifted out starting with bit 7. The last bit received resides in bit
position 0.
With the SPI configured as a Master, writing a data byte to this register initiates the data
transmission. With the SPI configured as a Slave, writing a data byte to this register loads
the shift register in preparation for the next data transfer with the external Master. In either
the Master or Slave modes, if a transmission is already in progress, writes to this register
are ignored and the Overrun error Flag, OVR, is set in the SPI Status Register.
When the character length is less than 8 bits (as set by the NUMBITS field in the SPI Mode
Register), the transmit character must be left justified in the SPI Data Register. A received
character of less than 8 bits is right justified (last bit received is in bit position 0). For
example, if the SPI is configured for 4-bit characters, the transmit characters must be
written to SPIDATA[7:4] and the received characters are read from SPIDATA[3:0].
