TPU

The Time Processor Unit (TPU), is co-processor on the MPC5xx microcontroller family that is used to implement the majority of the module's IO. The TPU is optimized to handle timer like functions, which frees up execution on the core MPC5xx based microcontroller. The MPC5xx has two, and sometimes three, of these co-processors. MotoHawk abstracts the usage of the TPU, but some restrictions on IO usage result from channel allocation. Some blocks like the Mux PSP considerations consume neighbouring channels, and others like Synchronized PWM Child block requires all parent child resources to exist on the same bank.
