FIRMWAR
E
• Added description of the CRC calculation method below the table “Boot
Mode Header (BMHD)”
SCU/CCU • Updated divider formula in registers CCUCON6,7,8.
• Updated table “CCU allowed Clock Ratios”.
SCU/SCU • Corrected DTSCON.CAL width.
• Removed design related register reference from “OCDS Behavior of
WDTs”.
PORTS • Corrected description of LVDS pads in CMOS mode: removed
sentence ´no open-drain mode available´
MTU • MCONTROL.Res4 field (bits 14:12) marked as “Must be written with
0x4” in to maintain redundancy.
• Sections “Reading a Single Memory Location” and “Writing a Single
Memory Location” should always write MCONTROL with the MS nibble
0x4 instead of 0x0.
• Design related register reference “RDR” removed.

,
SMU • Corrected register long name of SMU_RTC to “Recovery Timer
Configuration”.
• DMA alarm ALM2[24] is now reserved. Alarm implemented by DMA SRI
error detection alarms.
• Improved description of alarm ALM3[27].
• SCU alarm ALM3[28] is now reserved. Feature not implemented.
• Pre-alarms PreAlarm[129=DMA.(Safety FF Error Detection)] and
PreAlarm[130=PMU.(Safety FF Error Detection)] removed because
DMA and PMU do not implement Safety FF.
• Added configuration hints to SMU_AG<n>CF<m> Registers: reserved
alarms shall be configured as “No Action”.
• Enhanced description of register SMU_RMEF and SMU_RMSTS.
• Enhanced description of register SMU_PCTL with advice how to
operate it in the application.
• Changed section “SMU Integration Guidelines”.
• Explained “Register Monitor” = “Safety Flip-Flop”.
• Improved Figure “SMU State Machine”.
• Improved section “FSP Fault State”.
