IXD1110 Demo Board
6.0Optional Configurations
6.1Reset Jumper JP2
6.1.1Standard Operation
The Reset Jumper JP2 is required for standard operation of the IXD1110 demo board. Use the HRESET position for standard operation.
The POR position is not recommended for standard operation of the IXD1110 demo board. This configuration only affects the CPU operation, and does not affect IXF1110 operation. The only difference between HRESET and POR is that POR also resets the CPU PLLs and state machines. This difference is seen when reset is asserted by pressing switch S1. For more information on the POR position of JP2, refer to Table 12 (MPC860 Reset Responses) of the Motorola* MPC860 CPU Datasheet.
6.2JTAG Test Signals
The boundary scan test port for the IXF1110 is accessed using JP1 for
Note: For normal IXD1110 demo board operation, connect TRST_N pin 8 on JP1 to ground by jumpering pins 6 and 8 of JP1.
