21A.13 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 programmer mode (see table 21A-13) and input a 12
MHz input clock.
Table 21A-13 shows the pin settings for programmer mode.

21A.13.1 Socket Adapter and Memory Map
In programmer mode in which the PROM writer is used, reading from memory (verification),
writing, and initializing the flash memory (erasing all of its contents) are enabled. At this time, a
dedicated conversion socket adapter must be attached to a general-purpose PROM writer. Table
21A-14 shows the types of the socket adapters. For programmer mode on this LSI, one of the
socket adapters listed in table 21A-14 should be used.
