19. Flash Memory (F-ZTAT Version)
and a transition can be made to verify mode. The error protection state can be cancelled by the
power-on reset only.
19.10 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).
19.11 Usage Note
19.11.1 Module Standby Mode Setting
Access to flash memory can be enabled/disabled by the module standby control register
(MSTCR1). The initial value enables access to flash memory. Flash memory access is disabled
by setting the module standby control register. For details, see section 24, Power-Down
Modes.
19.11.2 Notes when Converting the F-ZTAT Versions to the Masked-ROM Versions
Please note the following when converting the F-ZTAT versions to the masked-ROM versions,
with using the F-ZTAT application software.
In the masked-ROM version, addresses of the flash memory registers (refer to section 25.1,
Register Addresses Table (In the Order from Lower Addresses)) return undefined value if read.
When the F-ZTAT application software is used in the masked-ROM version, 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 masked-ROM version, boot mode pin setting should not be performed.
Note: This difference applies to all the F-ZTAT versions and all the masked-ROM versions that
have different ROM size.
