Note: The user must ensure that Block Writes do not cross a 64 byte boundary within one operation.
5.8 USER ISP AND VIRTUAL E
The following commands will support transferring blocks of
data from RAM to flash program memory, and vice-versa.
The user is expected to enforce application security in this
case.
• Erase the entire flash program memory (mass erase).
• Erase a page of flash memory at a specified address.
• Read a byte from a specified address.
• Write a byte to a specified address.
NOTE: Execution of this command will force the device
into the MICROWIRE/PLUS ISP mode.
