EPP Address Port
SPP Control Port
SPP Status Port
4•12•1
EPP is an Enhanced Parallel Port which is one of IEEE 1284 data transfer mode. EPP is an extension to the register
definitions for the standard parallel port called SPP. See
When both Parallel connector P20 and BDM Debug Connector P12 are connected,
priority will be to on board serial command converter or EPP transfer mode via P20.
Default host selection is SPP Transfer Mode.
When the Host computer will begin an EPP negotiation access, MPC852TADS will switch to EPP Transfer Mode.
For EPP negotiation please refer to IEEE 1284 EPP Protocol.
