Serial Peripheral Interface (SPI) Module
16.12.3 SPI Data Register
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

Use this formula to calculate the SPI baud rate:
Baud rate =
Address: $0012
Do not use read-modify-write instructions on the SPI data register since the
register read is not the same as the register written.
