Conversion board configuration
IEA-SPC58NH-BGA302
Conversion board IEA-SPC58NH-BGA302 consist of 39 DIP switches, which define which altern-
ate port is connected to a specific CPU pin.
With the original microcontroller in the BGA302 package, this is configured through the applica-
tion software. However, when using the Emulation Adapter based on the BGA386 "superset"
device, this configuration has to be performed manually through jumpers DIP1-DIP39 since for
some reason each of the alternate ports is routed to an individual physical pin on the BGA386
device without the possibility for controlling routing by means of application software.
For example, with the original microcontroller in the BGA302 package, the application software
can route either port PQ[15] or port PA[0] to pin A17. However, with the “superset” microcontrol-
ler in the BGA386 package, port PQ[15] is fixed connected to pin L22 and port PA[0] to pin B18.
Hence with the Emulation Adapter you can define with the jumper DIP1 whether port PQ[15] or
port PA[0] is routed to target pin A17 on the 302-pin conversion board.
Set all the DIPs accordingly to exactly match with your application software configura-
tion. Any mismatch in configuration will yield application not operating properly!
DIPs are by default in position 1-2 (enabled).
