New SIU_PCR registers added (control the electrical characteristics of TXDC
and RXDC pins respectively:
• SIU_PCR[244]
• SIU_PCR[245]
New SIU_PCR registers added (control the electric characteristics of some
calibration bus pins):
• SIU_PCR336
• SIU_PCR338
• SIU_PCR339
• SIU_PCR340
• SIU_PCR341
• SIU_PCR342
• SIU_PCR343
• SIU_PCR345
Added clarification to eQADC Trigger Input Select Register (SIU_ETISR)
section.
New register added: Core MMU PID Control Register (SIU_EMPCR0). Provides
capability of real-time modification of MMU entries.
GPIO function added to SIU_PCR219 register. Also added 2-bit PA field.
Section 16.7, "Memory map and register
notation for DSPI:
- PCSxn or DSPI_x_CS[n] is now DSPI_x_PCS[n]
- SOUTx is now DSPI_x_SOUT
- SINx is now DSPI_x_SIN
- SCKx is now DSPI_x_SCK
SIU address map: Added page index 'Location' column
Removed "Pin" column from PCR PA values tables (incl. table in Sample PCR
map)
Pad Configuration Register (SIU_PCR12): Replaced "DATA[0]" with "DATA[16]"
in footnotes
SIU_PCR113 PA values: Change name TCR_A to TCRCLKA
SIU_PCR138 to SIU_PCR143 PA values tables: Added footnote explaining that
the eTPU function controlled by these registers has an additional
dependency on the SIU_ISEL8 register settings
SIU_PCR143 PA values: Corrected PA value for ALT2—was 0b0100; is 0b100
Updated
Section 16.7.15.138, "Pad Configuration Register 219 (SIU_PCR219)
SIU_PCR228 PA values: Changed PA value for TDO—was '—'; is '01'
SIU_PCR232 PA values: Changed pin and associated content from "EMIOS[5]
output only" to "TDI"
