Serial ROM Write Protect Jumper (JP9)
The serial ROM write protect jumper (
JP9
) protects the entire contents of
the memory device (M24C02) from inadvertent write operations. By
default,
JP9
has a jumper installed, making the memory a read-only
device. The default setting ensures that any hardware or software revision
information stored in the ROM is preserved. Remove
JP9
when you need
to write to serial ROM (see Table 2-8 ).
