MPC8349E-mITX-GP Board
1.6
This section describes the operational mode and configuration options of the MPC8349-mITX-GP board.
1.6.1
The Flash memory bank is MX29LV640MTTC-90 top boot Flash memory devices. Each Flash memory
bank has 135 sectors. The first 127 sectors, SA[0–126], are 64 Kbyte, and the last 8 sectors, SA[127–134],
are 8 Kbyte. These last 8 sectors can be write-protected to prevent accidental erasure of the sector content
for applications that may choose to use this protection feature.
write-protect sectors SA[127–134] of Flash memory.
1.6.2
An on-board serial EEPROM allows storage of miscellaneous board-related data. The EEPROM can be
write-protected by S2.SW3, as shown in

Jumper Off
Jumper On
CPU Power-on reset source jumper. CPU Power-On Reset can be controlled by a hardware MAX811 reset
chip (jumper 2–3 as default).
Real time clock selector. CPU real time clock interrupt request can be selected from DS1339 real time clock,
[ jumper 2–3]. Default is not selected.
Reset configuration word source selection jumpers
System reset button. Resets the MPC8349E-mITX-GP board.
Power-on push button. Powers up the MPC8349E-mITX-GP board.
SW0 and SW1. Controlled by the I2C expander connected to the MPC8349E
USB port power indicator LED. Lights when power is enabled on USB (D8).
3.3 V Active. On means 3.3 V power is good.
