JP1 Flash

memory

selection

JP1 selects the Flash memory

input, either sourced by

the TIP or by the router

board’s Am186CC

microcontroller. This allows

the TIP to program the

Am29F800 Flash memory on

the router board.

JP5 8/16-bit boot Selects 8- or 16-bit boot from

UCS

space. Enables booting

from 8-bit TIP memory.
