19.22.3 Programmer Mode Operation
Table 19-40 shows how the different operating modes are set when using programmer mode, and table 19-41 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
