15.8.3 PROM Mode Operation
Table 15.10 shows how the different operating modes are set when using PROM mode, and table
15.11 lists the commands used in PROM 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 6 signal. In status read mode, error information is output if an
error occurs.
