Section 18 Flash Memory (F-ZTAT Version)
18.10 PROM Programmer Mode
In PROM programmer mode, a PROM programmer can be used to perform programming/erasing
via a socket adapter, just as for a discrete flash memory. Use a PROM programmer that supports
the Renesas 256-kbyte flash memory on-chip MCU device type (FZTAT256V3A).
18.11 Usage Note
• Setting module standby mode
For flash memory, this module can be disabled/enabled by the module standby control register.
Flash memory operation is enabled for the initial value. Accessing flash memory is disabled
by setting module standby mode. For more information, see section 21, Power-Down Modes.
18.12 Notes when Converting the F-ZTAT Versions to the Mask-ROM
Versions
Please note the following when converting the F-ZTAT versions to the mask-ROM versions, with
using the F-ZTAT application software.
In the mask-ROM version, addresses of the flash memory registers (refer to appendix A.1,
Register Addresses (Order of Address)) return undefined value if read.
When the F-ZTAT application software is used in the mask-ROM versions, the FWP pin level
cannot be determined. When converting the program, make sure the reprogramming
(erasing/programming) part of the flash memory and the RAM emulation part not to be initiated.
In the mask-ROM versions, boot mode pin setting should not be performed.
Note: This difference applies to all the F-ZTAT versions and all the mask-ROM versions that
have different ROM size.
