• Added TQFP-144 package option to TC21x.
• Added SAL package option to all devices.
SCU/CCU • Removed documentation of internal oscillator load caps (“adjustable
Load Caps”) as these are not implemented.
SCU/SCU • Corrected DTSCON.CAL width.
• Removed design related register reference from “OCDS Behavior of
WDTs”.
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.
