17.20.3 Programmer Mode Operation
Table 17.35 shows how the different operating modes are set when using programmer mode, and
table 17.36 lists the commands used in programmer mode. Details of each mode are given below.
Memory Read Mode: Memory read mode supports byte reads.
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.
Auto-Erase Mode: Auto-erase mode supports automatic erasing of the entire flash memory.
Status polling is used to confirm the end of auto-erasing.
Status Read Mode: Status polling is used for auto-programming and auto-erasing, and normal
termination can be confirmed by reading the I/O
output if an error occurs.
