H'0000
Address in
PROM mode
H'0000
On-chip PROM
H'3FFF
H'3FFF
Uninstalled area*
H'1FFFF
Note: * ^{The output data is not guaranteed if this address area is read in PROM mode. There-}
fore, when programming with a PROM programmer, be sure to specify addresses
from H'0000 to H'3FFF. If programming is inadvertently performed from H'4000 on-
ward, it may not be possible to continue PROM programming and verification.
When programming, H'FF should be set as the data in this address area (H'4000 to
H'1FFFF).
