In the on-board programming modes (user mode and user program mode), NMI input should be
disabled to give top priority to the program/erase operations (including RAM emulation).
18.11
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 PLLx2 mode (see table 18.9) and input a 6 MHz input
clock, so that the SH7050 runs at 12 MHz.
Table 18.9 shows the pin settings for programmer mode. For the pin names in programmer mode,
see section 1.3.3, Pin Assignments.
