16.6.15.161Pad Configuration Register 345 (SIU_PCR345)
NOTE
Unlike other pad configuration registers (PCRs), which control the function
and electrical characteristics of one pin, this register controls the function
and electrical characteristics for a group of pins on the Calibration bus.

16.6.15.162Pad Configuration Register 350 – 381 (SIU_PCR350 – SIU_PCR381)
The SIU_PCR350 – SIU_PCR381 registers control the muxing of the signals to the DSPI. PA field values
are shown in
Table 16-198 .
