9.8.5.3 Erasing Shadow Information Words
9.8.6 Erase Pulse Amplitude and Width Modulation
MMC2107 – Rev. 2.0
MOTOROLA
NOTE:
NOTE:
The shadow information words are erased with either array block 0
depending upon the array configuration. To verify that the shadow
information words are erased with block 0, erase margin reads should
be performed with the SIE bit set in CMFRMCR while the shadow
information is read. For the erase operation to be completed, block 0
must also be fully verified.
Setting SIE = 1 disables normal array access and should be cleared
after verifying the shadow information.
Refer to
of the FLASH.
The values of PAWS[2:0] and NVR should be updated on the
appropriate pulse to change the erase voltage.
GDB = 0 for all erase operations.
Margin reads are required after the first –9-V pulse.
