Peripheral Chip Select Strobe on MCF54415

[SeeCwriter]

In the MCF54415 Reference Manual, section 40.2, it refers to a Peripheral Chip Select strobe (PCSS) that can be used for deglitching SPI bus chip select signals (PCS), and that it is enabled by setting the PCSSE bit in the DSPI_MCR register of the selected SPI module.

However, there is no PCSSE bit in the MCR register (see figure 40.2), and I can't find any pin labeled for PCSS. Can someone enlighten me about this?
