1.176-pin and 208-pin packages have 34 input channels; 144-pin package has 32; 100-pin package has 23.
— Double match/capture channels
— Angle clock hardware support
— Nexus Class 1 Debug support
— Enhancements to make DMA and interrupt operation more flexible
— New programmable channel mode, for increased flexibility of channel hardware
— Scheduler priority-passing mechanism can be disabled
— New Watchdog mechanism kills threads over a programmable timeout
— New counter allows microengine load information collection for performance analysis
— Channels 1 and 2 (besides channel 0) can now be selected to control the EAC
— Timebase prescalers are now reset when the GTBE input is negated, guaranteeing synchronization with eMIOS in
— New MISC flag indicates when an SCM signature calculation round is completed. This allows
— New channel TCCEA flag allows continuous capture even after TDLA is set, making it fully compatible with TPU
— New branch condition PRSS tells the pin state at the time when a channel (match or transition)
— MRLEA/B can now be negated independently by microcode
— New Engine Relative address mode allows a function to access SDM address space common to one engine, but
Enhanced queued A/D converter (eQADC)
— Two independent on-chip RSD Cyclic ADCs
— Automatic application of ADC calibration constants
— Up to 34
— Four pairs of differential analog input channels
— Full duplex synchronous serial interface to an external device
