Erase FlashEE (E)

AN2183

MOTOROLA

Read FlashEE (R)

After entering the single character R, followed by either "1" or "2", the

program will respond by outputting the most recent data byte block. In

the example shown, the first time R is entered and the FlashEE is erased

as indicated by the software’s response. Subsequent examples show

the current data block data being reported back to the host.

This command will directly execute the EEErase subroutine and erase

the selected FlashEE section.
