Enhanced Time Processing Unit (eTPU)
For more detailed information regarding the eTPU module, refer to the eTPU User’s Manual. The
MCF5235 devices contain a subset of the eTPU’s full functionality. This chapter will focus only
on an eTPU overview and those details that are different than the full instantiation of the module.
These differences include:
Because of these differences, full register bit descriptions are included within this chapter as well.

• Only one eTPU engine: eTPU A in the eTPU User’s Manual. Ignore any references to
• The eTPU Debug interface is built into the MCF5235’s debug module. Refer to
• 6 Kbytes of shared code memory (SCM) and 1.5 Kbytes of shared data memory (SDM).
• Data transfer requests are implemented as a single DMA request to the MCF5235’s DMA
• Each I/O channel pair is shared on a common pin. Therefore, output buffer enable (OBE)
• The MCF5232 and MCF5234 devices only contain a 16 channel eTPU. Therefore, the
eTPU B and the Shared Timer and Counter (STAC) bus.

LTPUODIS and UTPUODIS signals control only eight channels each, TPUCH[7:0] and
TPUCH[15:8] respectively. The MCF5233 and MCF5235 has the full 32 channel eTPU, so
