8. Do not perform additional programming. Erase the memory before reprogramming.
In on-board programming, perform only one programming operation on a 128-byte
programming unit block. Programming should be carried out with the entire programming unit
block erased.
9. Before programming, check that the chip is correctly mounted in the PROM writer.
Overcurrent damage to the device can result if the index marks on the PROM writer socket,
socket adapter, and chip are not correctly aligned.
10. Do not touch the socket adapter or chip during programming.
Touching either of these can cause contact faults and write errors.
11. A wait time of 100 µs or more is necessary when performing a read after a transition to
normal mode from program, erase, or verify mode.
12. Use byte access on the registers that control the flash memory (FLMCR1, FLMCR2,
EBR, and RAMCR).
