11.8 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.

• Copy a block of data from RAM into flash program
• Copy a block of data from program flash memory to RAM.
The following table lists the User ISP/Virtual E
required parameters and return data, if applicable. The com-
mand entry point is used as an argument to the JSRB
instruction. Table 12 lists the Ram locations and Peripheral
Registers, used for User ISP and Virtual E
pected contents. Please refer to the COP8 FLASH ISP User
Manual for additional information and programming ex-
amples on the use of User ISP and Virtual E
memory.
