Signal Description
1722
Change in signal name notation for DSPI signals:
• 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
Change in signal name notation for CAN signals:
CNTXx is now CAN_x_TX
CNRXx is now CAN_x_RX
Change in signal name notation for SCI signals:
RXDx is now SCI_x_RX
TXDx is now SCI_x_TX
Pin 96 added to list of VSS pins for 176-pin package
GPIO[219] and MCKO pins are both controlled by SIU_PCR219, which does not
have a PA field. Both are single-function pins. See SIU_PCR219 section in SIU
chapter for details.
Clarification: Following signals are active low:
• (EBI) CS[0:3]
• (EBI) BDIP
• (EBI) OE
• (EBI) TA
• (EBI) TS
• (EBI) RD_WR
• (EBI) WE[0:1]/BE[0:1]
• (Nexus) MSEO[0:1]
• (Nexus) RDY
• IRQ[0:15]
• (FlexRay) FR_A_TX_EN
• (FlexRay) FR_B_TX_EN
Note added to MultiV pads: Multivoltage pads are automatically configured in
low swing mode when a JTAG or Nexus function is selected, otherwise they are
high swing.
Note added to VDDEH7 voltage on AN12-AN15: For pins AN12-AN15, if the
analog features are used the VDDEH7 input pins should be tied to VDDA
because that segment must meet the VDDA specification to support analog
input function.
Added VRL, VRH, and REFBYPC functions after reset.
Clarification: "10" on BOOTCFG[0:1] causes boot from external memory using
