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 I2C address immediately

when accessed.

Refer to the full data sheet.

For 1 O tPROG or 8 O tPROG depending on the parameter byte, counted from the

rising SCL edge of the parameter byte acknowledge bit.
