6.10.2 Programmer Mode Commands
The following commands are supported in programmer mode.
• Memory Read Mode
• Auto-Program Mode
• Auto-Erase Mode
• Status Read Mode
Status polling is used for auto-programming, auto-erasing, and status read modes. In status read
mode, detailed internal information is output after the execution of auto-programming or auto-
erasing. Table 6.13 shows the sequence of each command. In auto-programming mode, 129 cycles
are required since 128 bytes are written at the same time. In memory read mode, the number of
cycles depends on the number of address write cycles (n).
