8. Caution
• Please review the MBM29LV400TC data sheet in conjunction with this document.
• CPU mode
When in CPU mode, the address-allocation method is different than when writing via a parallel Flash
programmer. Refer to “3.1 Address conversion from CPU Mode to Flash Programming Mode (Page
No.995)”.
• Flash memory mode (writing via parallel Flash programmer)
This Flash memory allows writing via an external device, by means of the parallel Flash programmer. In this
state, pin functions equivalent to the stand-alone product MBM29LV400TC are assigned to the device's
external pins, and operation of the CPU halts.
In Flash memory mode, the address line connections are changed from CPU mode, to mapping within the
memory area.
• See the section in your parallel Flash programmer manual concerning the MBM29LV400TC or MB91460 for
details about using Flash memory from a parallel Flash programmer.
