19.11.2 Operation in Programmer Mode

Table 19.12 shows how the different operating modes are set when using programmer mode, and

table 19.13 lists the commands used in programmer mode. Details of each mode are given below.

â¢ Memory Read Mode

Memory read mode supports byte reads.

â¢ Auto-Program Mode

Auto-program mode supports programming of 128 bytes at a time. Status polling is used to

confirm the end of auto-programming.

â¢ Auto-Erase Mode

Auto-erase mode supports automatic erasing of the entire flash memory mat. Status polling is

used to confirm the end of auto-erasing.

â¢ Status Read Mode

Status polling is used for auto-programming and auto-erasing, and normal termination can be

confirmed by reading the I/O6 signal. In status read mode, error information is output if an

error occurs.

2. *Ain indicates that there is also address input in auto-program mode.

3. For command writes in auto-program and auto-erase modes, input a high level to the

FWE pin.
