TPU3 ROM Functions
The following pages provide brief descriptions of the pre-programmed functions in the TPU3. For detailed
descriptions, refer to the programming note for the individual function. The Freescale
TPU Literature
Pack
provides a list of available programming notes.
D.1
Overview
The TPU3 contains 4 Kbytes of microcode ROM. It can have up to 8 Kbytes of memory and a maximum
of four entry tables (see
). This appendix defines the standard ROM functions for the
MPC561/MPC563.
Figure D-1. TPU3 Memory Map
The TPU3 can address up to 8 Kbytes of memory at any one time. It has 4 Kbytes of internal ROM, located
in banks 0 and 1, and 8 Kbytes of dual-ported SRAM (DPTRAM), located in banks 0, 1, 2, and 3. As only
one type of memory can be used at a time, the TPU3 must either use the internal ROM or the SRAM.
Functions from both memory types cannot be used in conjunction.
A new feature of the TPU3 microcode ROM is the two 16-function entry tables in the 4 Kbytes of internal
ROM. The ETBANK field in the TPUMCR2 register, written once after reset, determines which one of
