19.2.2
When the mode pins and the FWE pin are set in the reset state and a reset-start is executed, the
SH7050 enters one of the operating modes shown in figure 19.2. In user mode, flash memory can
be read but not programmed or erased.
Flash memory can be programmed and erased in boot mode, user program mode, and programmer
mode.
