Product data
Fig 5. Auto increment memory address; two byte write.
After the receipt of each data byte, the six high-order bits of the memory address
providing access to one of the 64 pages of the memory remain unchanged. The five
low-order bits of the memory address will be incremented only (see
these five bits a single byte within the page in access is selected. By an increment the
memory address may change from 31 to 0, from 63 to 32, etc. If the master transmits
more than 32 bytes prior to generating the STOP condition, data within the addressed
page may be overwritten and unpredictable results may occur. As in the byte write
operation, all inputs are disabled until completion of the internal write cycles.
Remark: Write accesses to the EEPROM are enabled if the pin WP is LOW. When
WP is HIGH the EEPROM is write-protected and no acknowledge will be given by the
PCF85116-3 when data is sent. However, an acknowledge will be given after the
slave address and the word address.
