The two Flash memory banks are 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.
settings to 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
1.6.3
An M66EN input pin determines the AC timing of the PCI interface. On the MPC8349E-mITXE board,
the state of this signal can be driven to 0 by the J22 jumper to select 33 MHz AC timing. If J22.F is not
driven to 0, the M66EN signal level is determined by the PCI agent card connected to PCI slot P1. If a 33
MHz only card is inserted, the M66EN signal is driven to 0 by the PCI agent card according to the PCI
specification, or it is driven to 1 if it can perform at 66 MHz. See

M66EN signal is determined by the card plugged into the PCI slot (PCI 32-bit slot and MiniPCI slot).
M66EN signal is hardwired to 0, which is hard coded to 33 MHz PCI operation.
