TMS320C54XX Evaluation Module Technical Reference

2.10.1 Jumper Positions

The figure 2-1 shows the locations of the jumpers on the EVM320C54XX EVM.

2.10.2 JP1, UART Reset

Jumper JP1 is used to select either a system reset from P5, pin4 DTR line or to connect

the DTR line to the UART’s CTS pin. When position 1-2 is selected the DTR activates

the reset. The 2-3 position connects DTR to CTS. The table below shows the positions

and their functions:

2.10.3 JP2, Onboard UART CTS Routing

Jumper JP2 can be used to configure the source of the CTS signal on the onboard

UART. When position 1-2 is used the pin 4 in P5 is used as the CTS input. If position

2-3 is selected pin 7 on P5 is used as the CTS input. The jumper settings are shown in

the table below:

2.10.4 JP3, A15/A17 Select

Jumper JP3 allows the selection of memory address MA15 with either processor

address A15 or A17. The table below shows the two positions and their functions:
