[MPC5746R] Inconsistent information between DSPI and IO Port in Reference Manual

[namnguyenviet]

Hello,

I have a concern in Reference Manual from customers, which is a mismatch between supported DSPI CS pins and corresponding CS IO Port pins.

DSPI2 can support PCS0-3, however there is an available CS4 pins for DSPI2 in IO Signal description. With DSPI1, it can support PCS0-4, however there is no CS4 for DSPI1, so I supposed there might be a typo here between DSPI1 and DSPI2.

Does anyone have experience about this situation?

Hi Nam,

here is the feedback:

After confirmed with design the RM Table 48-1will be updated as below.

DSPI_1 only supports Chip Select 0 to 3.  ( DSPI_1 PCS4 not supported)

DSPI_2 supports Chip Selects of 0 to 4. (DSPI_2 supports PCS4 )

IO signal excel contains the correct information.

Regards,

Lukas
