entered by re-setting the P1 or E1 bit. However, PV1 and EV1 bit setting is enabled, and a
transition can be made to verify mode. Error protection can be cleared only by a power-on reset.

In 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 128-kbyte flash memory on-chip MCU device type (FZTAT128V5A).

In user mode, the flash memory will operate in either of the following states:
Table 19.6 shows the correspondence between the operating modes of the H8S/2628 Group and
the flash memory. When the flash memory returns to its normal operating state from standby
mode, a period to settle the power supply circuits that were stopped is needed. When the flash
memory returns to its normal operating state, bits STS2 to STS0 in SBYCR must be set to provide
a wait time of at least 20 µs, even when the external clock is being used.
