Section 17 ROM
• When performing programming using PROM mode on a chip that has been
programmed/erased in an on-board programming mode, auto-erasing is recommended before
carrying out auto-programming.
Notes: 1. The flash memory is initially in the erased state when the device is shipped by Renesas
Technology. For other chips for which the erasure history is unknown, it is
recommended that auto-erasing be executed to check and supplement the initialization
(erase) level.
2. Auto-programming should be performed once only on the same address block.
Additional programming cannot be carried out on address blocks that have already
been programmed.
