The abbreviations have the same significance as in Table 9 with the exception of the "DO CARE" entries. It is only when this bit is "1"

that the corresponding digit is taken into consideration on page request. For example, a page defined as "normal" or one defined as

"timed" may be selected.

If "HOLD" is low the page is held. The addressing of successive bytes via the I2C is automatic.
