Selecting the Flash Memory
Jumper block 1 (JP1) selects which Flash memory is used, either the internal (TIP
board) or the external (host board) Flash memory. To select the use of the internal
8-bit DIP Flash, jumper pins 2 and 3 on JP1 and drive a logic low to the FLASHCS
signal (pin 58 of P1 of the main interface connector). To select the use of the host
board Flash, jumper pins 1 and 2 on JP1. Figure 2-13 indicates the pin locations
on JP1.
