Change in signal name notation for DSPI, CAN and SCI signals:
DSPI:
PCS_x[n] is now DSPI_x_PCS[n]
SOUT_x is now DSPI_x_SOUT
SIN_x is now DSPI_x_SIN
SCK_x is now DSPI_x_SCK
CAN:
CNTXx is now CAN_x_TX
CNRXx is now CAN_x_RX

Updates to DC electrical specifications:
V
Updated I/O pad current specifications
Updated I/O pad V
Corrections to Nexus timing:
• Slew rate on power supply pins specification changed to 25 V/ms (was 50 V/ms)
• Maximum Nexus debug port operating frequency is 40 MHz in all configurations
• To route Nexus to MDO, clear NPC_PCR[NEXCFG] (formerly this was documented as
• To route Nexus to CAL_MDO, set NPC_PCR[NEXCFG]=1 (formerly this was
OH_LS
NPC_PCR[CAL]
documented as NPC_PCR[CAL]
