Freescale Semiconductor
PXR40 Microcontroller Reference Manual, Rev. 1
In Slave Mode, the DSPI generates a trigger pulse on the MTRIG pin when a rising or falling edge is
detected on HT. Which edge that generates an output pulse is selected by the TPOL bit in the
DSPI_DSICR.

Memory Map and Register Definition
25.3.1
Memory Map
Register accesses to memory addresses that are reserved or undefined result in a transfer error. Write
access to the DSPI_POPR register also result in a transfer error.
