Page write:
initiated in the same manner as the byte write operation. The master can transit eight
data bytes within one transmission. After receipt of each byte, the PCF8582C-2 will
respond with an acknowledge. The typical E/W time in this mode is
9
and sequential writing of these 8 bytes another typical 28 ms.
After the receipt of each data byte, the three low-order bits of the word address are
internally incremented. The high-order five bits of the address remain unchanged.
The slave acknowledges the reception of each data byte with an ACK. The I
data transfer is terminated by the master after the 8th byte with a STOP condition. If
the master transmits more than eight bytes prior to generating the STOP condition,
no acknowledge will be given on the ninth (and following) data bytes and the whole
transmission will be ignored and no programming will be done. As in the byte write
operation, all inputs are disabled until completion of the internal write cycles.
