IEA-SPC58NH-TQ176
Conversion board IEA-SPC58NH-TQ176 consist of 36 jumpers which define which alternate port
is connected to a specific CPU pin.
With the original microcontroller in the QFP176 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 J1-J36 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 QFP176 package, the application software
can route either port PQ[15] or port PA[0] to pin 137. 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 J1 whether port PQ[15] or
port PA[0] is routed to target pin 137 on the 176-pin conversion board.
Set all the jumpers accordingly to exactly match with your application software configura-
tion. Any mismatch in configuration will yield application not operating properly!
Jumpers are by default set to position 1-2.
