Function
‘W 5
Address MSB LSB
The EEPROM is written with the data
MSB
and
LSB
at
the specified
Address
Operation:
The module will write the EEPROM memory at the specified Address with the data
contained in the MSB and LSB bytes.
Special Conditions:
All EEPROM functions must be sent as a single 5-byte packet. A Write Enable
command must be sent before any Write or Erase commands can be performed.
The user cannot write addresses 0-4 at any time. The EEPROM cannot be written
or erased if the J2 jumper is on.
Example:
Winsock1.
