16-Bit CPU12X
— Upward compatible with MC9S12 instruction set with the exception of five Fuzzy instructions
— Enhanced indexed addressing
— Additional (superset) instructions to improve 32-bit calculations and semaphore handling
— Access large data segments independent of PPAGE
Enhanced Interrupt Module
— Eight levels of nested interrupts
— Flexible assignment of interrupt sources to each interrupt level
— One non-maskable high priority interrupt (XIRQ)
— Wake-up Interrupt Inputs
Memory Protection Unit (MPU)
— 4 address regions definable per active program task
— Address range granularity as low as 256-bytes
— Protection Attributes
— Non-maskable interrupt on access violation
XGATE
— Programmable, high performance I/O coprocessor module – up to 100 MIPS RISC
— Transfers data to or from all peripherals and RAM without CPU intervention or CPU wait states
— Performs logical, shifts, arithmetic, and bit operations on data
— Can interrupt the HCS12X CPU signalling transfer completion
— Triggers from any hardware module as well as from the CPU possible
— Two interrupt levels to service high priority tasks
— Enables Full CAN capability when used in conjunction with MSCAN module
(MEM, WAV, WAVR, REV, REVW) which have been removed.
