16.5.2 READE2 COMMAND 03_HEX
16.5.2.1 Overview
Command _Codehex
Action
ReadE2
03
Reads data from E²PROM and puts it to the
FIFO buffer
Arguments
Start Address LSB
Start Address MSB
Number of Data Bytes
Returned Data
Data Bytes
The ReadE2-Command interprets the first two bytes found in the FIFO buffer as E²PROM starting
byte-address. The next byte specifies the number of data bytes that shall be returned.
When all three argument-bytes are available in the FIFO buffer, the specified number of data bytes is copied
from the E²PROM into the FIFO buffer, starting from the given E²PROM starting byte-address.
The ReadE2-Command can be triggered only by the µ-Processor. It stops automatically when all data has
been delivered.
Note: It is strictly recommended to use only the described E²PROM address area.
