17.28.2 PROM Mode Operation
Table 17.57 shows the settings for the operating modes of PROM mode, and table 17.58 lists the
commands used in PROM mode. The following sections provide detailed information on each
mode.
• Memory-read mode: This mode supports reading, in units of bytes, from the user MAT or user
• Auto-program mode: This mode supports the simultaneous programming of the user MAT and
• Auto-erase mode: This mode only supports the automatic erasing of the entire user MAT or
• Status-read mode: Status polling is used with automatic programming and automatic erasure.
