• Manufacturer Part Number: AN1827
• Description: Programming and Erasing FLASH Memory on the MC68HC908AS60
• Manufacturer: Freescale Semiconductor / Motorola

AN1827
MOTOROLA
NOTE:
As a result, the beginning address of the block which will be erased is:
The end address of the block which will be erased is:
This results in erasing 64 bytes from address $9AC0 to $9AFF.
All memory arrays are shaped differently, so one row may not equal 64
bytes like on the MC68HC908AS60. Refer to the appropriate
documentation for the pertinent device and apply these same principles.
