[AK93C41A/51A]
Read
The read instruction is the only instruction which outputs serial data on the DO pin.
Following the Start bit, first Op code and address are decoded, then the data from the selected memory
location is available at the DO pin. A dummy bit (logical "0") precedes the 16-bit data from the selected
memory location. The output data changes are synchronized with the rising edges of the serial clock (SK).
The data in the next address can be read sequentially by continuing to provide clock. The address
automatically cycles to the next higher address after the 16bit data shifted out.
AK93C41A • • When the highest address is reached ($3F), the address counter rolls over to
address $00 allowing the read cycle to be continued indefinitely.
AK93C51A • • When the highest address is reached ($7F), the address counter rolls over to
address $00 allowing the read cycle to be continued indefinitely.
