The following bits should be written by the CPU32+ core before enabling the SPI.
E—Empty
Bits 14, 10, 8–2—Reserved
W—Wrap (Final BD in Table)
I—Interrupt
CM—Continuous Mode
This bit is valid only when the SPI is configured as a master; it should be written as a zero
in slave mode.

The number of Rx BDs in this table is programmable and is determined only by the

This allows continuous reception from an SPI slave into one buffer for autoscan-
ning of a serial A/D peripheral with no CPU overhead.
