Data destination, segment number (Table 7)
Transferring scratchpad data to user EEPROM pages;
If the target memory is write-protected, this command cannot not complete
successfully. Data is taken from the scratchpad location that corresponds to the
segment number. Example: segment 0 corresponds to SP+0 to SP+3, addresses
00h to 03h.
The data must first be written to the scratchpad.
The target memory must not be write-protected (locked).
If the target memory is write protected, the memory write cycles do not take place.
In that case the device is not busy and acknowledges its I
when accessed.
Refer to the full data sheet.
