The general command encoding used by the serial port for
EEPROM accesses is shown below in Device Access Examples,
where B2-0 is the block number, P2-0 is the page number within the
block and A3-0 is the byte address within the page. Bits denoted as
“x” are ignored by the device.

Page write: The PCA24S08 is capable of a 16-byte page write
operation. It is initiated in the same manner as the byte write
operation. The master can transit 16 data bytes within one
transmission. After receipt of each byte, the PCA24S08 will respond
with an acknowledge. The typical E/W time in this mode is 5 ms.
After the receipt of each data byte, the four low-order bits of the
word address are internally incremented. The six high-order bits of
the address remain unchanged. The slave acknowledges the
reception of each data byte with an ACK. The I2C-bus data transfer
is terminated by the master after the 16th byte of data with a STOP
condition. After a write to the last byte in a page, the internal
address is wrapped around to point to the beginning of that page. If
the master transmits more than 16 bytes prior to generating the
STOP condition, no acknowledge will be given on the 17th (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.
After this STOP condition, the E/W cycle starts and the I2C-bus is
free for another transmission.
During the E/W cycle the slave receiver does not acknowledge if
addressed via the I2C-bus.
