Enhanced Time Processing Unit (eTPU)
20.2
The eTPU engine is responsible for processing input pin transitions and output pin waveform
generation based on time bases, either internal or external. The eTPU engine has its own
microprocessor and dedicated hardware for processing signals on I/O pins.
The eTPU engine processor, hereafter called microengine, fetches microinstructions from shared
code memory (SCM). eTPU application parameters and work data is stored in shared data memory
(SDM). It is accessed by the MCF5235’s ColdFire core and the eTPU microengine. The Host
Interface allows the MCF5235’s ColdFire core to access eTPU registers, SDM, and SCM.
The eTPU engine interfaces with 32 I/O channels, each with hardware dedicated for input signal
processing and output signal generation. Each channel can also choose between two 24-bit counter
registers for its time base.
