Page Write
AK6416C has Page Write mode, which can write the data within 8 words with one programming
cycle. The input data sent to the shift register within 8 words. After the instruction input, the
internal programming cycle starts when CS pin changes low to high. After the instructions are
inputted, CS pin should change low to high after the last data bit (D0) inputs and before next SCK
clock rises. Page Write function can start only at this timing.
After the receipt of each word, the three lower order address pointer bits internally incremented by
one. The higher order seven bits of the word address remains constant. When the highest
address is reached ”XX XXXX X111”, the address counter rolls over to address ”XX XXXX X000”
allowing the page write cycle to be continued indefinitely.
If AK6416C is transmitted more than 8 words, the address counter will ”roll over” and the
previously written data will be overwritten. When AK6416C is transmitted 10 words, ninth word
will be overwritten to first word, and tenth word will be overwritten to second word.
During the automatic write time-out period ( Busy status) and while entering Page Write
instruction, the RESET pin should be low level. If the RESET pin is set to high level during the
automatic write time-out period, the AK6416C stops execution of internal programming and the
device returns to ready status. In this case the word data of the specified address will be
incomplete. When inputting the new instruction after RESET, the CS pin should be set to high
level. When the RESET pin is kept at high level, the Page Write is not executed. This becomes
write protection function.
The CS pin need not be high level during automatic write time-out period ( Busy status).
