Time Processor Unit 3
The time processor unit 3 (TPU3), an enhanced version of the original TPU, is an intelligent,
semi-autonomous microcontroller designed for timing control. The TPU3 is fully compatible to the TPU2.
Operating simultaneously with the CPU, the two TPU3 modules process micro-instructions, schedule and
process real-time hardware events, perform input and output, and access shared data without CPU
intervention. Consequently, for each timer event, the CPU setup and service times are minimized or
eliminated.
The MPC561/MPC563 contains two independent TPU3s: TPU_A and TPU_B. These two TPU3 modules
are memory mapped as shown in
