WRITE OPERATIONS
Byte/word write
For a write operation the PCX8582X-2 requires a second
address field. This address field is a word address
providing access to the 256 words of memory. Upon
receipt of the word address the PCX8582X-2 responds
with an acknowledge and awaits the next eight bits of data,
again responding with an acknowledge. Word address is
automatically incremented. The master can now terminate
the transfer by generating a stop condition or transmit up
to six more bytes of data and then terminate by generating
a stop condition.
After this stop condition the ERASE/WRITE cycle starts
and the bus is free for another transmission. Its duration is
7 ms (typ.) per byte.
During the ERASE/WRITE cycle the slave receiver does
not send an acknowledge bit if addressed via the I
2
C-bus.
PAGE WRITE
The PCX8582X-2 is capable of an eight-byte page write
operation. It is initiated in the same manner as the byte
write operation. The master can transmit eight data bytes
within one transmission. After receipt of each byte the
PCX8582X-2 will respond with an acknowledge. The
typical ERASE/WRITE time in this mode is
9
×
7 ms = 63 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. 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. As in the byte write operation,
all inputs are disabled until completion of the internal write
cycles.
