Serial Peripheral Interface (SPI)
20.14.3 SPI Data Register
Technical Data
328
NOTE:
Address: $0012
The SPI data register consists of the read-only receive data register and
the write-only 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 registers that can contain different values.
See
R7–R0/T7–T0 — Receive/Transmit Data Bits
Do not use read-modify-write instructions on the SPI data register since
the register read is not the same as the register written.
