The page write mode allows up to 16 bytes to be written in a single write operation in the S-24CS16A.
Basic data transmission procedure is the same as that in the “Byte Write”. But instead of generating a stop
condition, the master transmitts 8-bit write data up to 8 bytes before the page write.
When the E
start condition, it generates an acknowledge. Then the E
an acknowledge. After the E
write data corresponding to the next word address, and generates an acknowledge. The E
reception of 8-bit write data and generation of acknowledge in succession. The E
data as the maximum page size.
Receiving a stop condition initiates a write cycle of the area starting from the designated memory address and
having the page size equal to the received write data.
In S-24CS16A, the lower 4 bits of the word address are automatically incremented every time when the E
receives 8-bit write data. If the size of the write data exceeds 16 bytes, the upper 4 bits of the word address and
page address (P2, P1 and P0) remain unchanged, and the lower 4 bits are rolled over and previously received data
will be overwritten.
