5.5.2 EPROM Size Selection Jumpers
The EZ-KIT Lite supports 128K x 8, 256K x 8, 512K x 8, and 1M x 8 EPROMs, each of
which is selectable through jumpers JP4 and JP5. The EPROM socket is originally
populated with a 256K x 8 EPROM. If a different EPROM is used, JP4 and JP5 should
be adjusted to accommodate the different size. Table 5-4 shows the pins that the jumpers
for JP4 and JP5 should be connected to.

5.5.3 Processor ID Jumpers
During typical operation of the EZ-KIT Lite board, there is only a single DSP in the
system. Jumpers JP7 and JP8 should be checked to guarantee that the board is
configured as a single processor system. In the case where a second processor is
attached to the board through the expansion connectors, these jumpers should be changed
to configure the EZ-KIT Lites’ ADSP-21065L processor as processor 1 or processor 2 in
the multiprocessor system. The debug monitor will not properly boot from the EPROM
if the IDs are not configured for a single processor. System configuration options are
shown in Table 5-5.
