19.10 Note on Flash Memory Programming/Erasing
In the on-board programming modes (boot mode and user program mode), NMI input should be
disabled to give top priority to the program/erase operations (including RAM emulation).
19.11 Flash Memory Programmer Mode
Programs and data can be written and erased in programmer mode as well as in the on-board
programming modes. In programmer mode, flash memory read mode, auto-program mode, auto-
erase mode, and status read mode are supported. In auto-program mode, auto-erase mode, and
status read mode, a status polling procedure is used, and in status read mode, detailed internal
signals are output after execution of an auto-program or auto-erase operation.
In programmer mode, set the mode pins to crystal oscillation/PLLx4 mode (see table 19.11) and
use a 6 MHz crystal oscillator, so that the SH7065 runs at 24 MHz.
Table 19.11 shows the pin settings for programmer mode. For the pin names in programmer mode,
see figure 19.19.
