19.13.3 SPI Data Register
The SPI data register is the read/write buffer for the receive data register and the transmit data register.
Writing to the SPI data register writes data into the transmit data register. Reading the SPI data register
reads data from the receive data register. The transmit data and receive data registers are separate
buffers that can contain different values. (See
R7–R0/T7–T0 — Receive/Transmit Data Bits
Freescale Semiconductor
Address:
Do not use read-modify-write instructions on the SPI data register since the
buffer read is not the same as the buffer written.
