Functional Descriptions
WRITE Operations
BYTE WRITE
A write operation requires a word address following the slave address word (R/W=0) and
acknowledge. The word address is comprised of eight bits and provides access to any one of the
256 words. Upon receipt of the word address the AK6003A responds with an acknowledge, and
awaits the next eight bits of data, again, responding with an acknowledge.
The master then terminates the transfer by generating a stop condition, at which time the AK6003A
begins the internal write cycle to the nonvolatile memory. While the internal write cycle is in
progress the AK6003A inputs are disable, and the device will not respond to any requests from the
master.
BYTE WRITE
PAGE WRITE
The AK6003A is capable of a sixteen byte page write operation.
It is initiated in the same manner as the byte write operation. But instead of terminating the write
cycle after the first data word is transferred, the master can transmit up to fifteen more words. After
the receipt of each word, the AK6003A will respond with an acknowledge. The master then
terminates the transfer by generating a stop condition, at which time the AK6003A begins the
internal write cycle to the nonvolatile memory.
After the receipt of each word, the four lower order address pointer bits are internally incremented
by one. The higher order four bits of the word address remains constant. When the highest address
is reached (XXXX 1111), the address counter rolls over to address "XXXX 0000" allowing the read
cycle to be continued indefinitely.
If the master should transmit more than sixteen words prior to generating the stop condition, the
address counter will "roll over" and the previously written data will be overwritten. When the master
transmit eighteen words prior to the stop condition, seventeenth word will be overwritten to first
word, and eighteenth word will be overwritten to second word.
