SERIAL DATA TRANSFER APPARATUS, SERIAL DATA TRANSFER METHOD, IMAGE FORMATION APPARATUS, AND RECORDING MEDIUM

摘要

A serial data transfer apparatus includes a decoder, a counter, and a calculation circuit. The decoder is configured to decode serial data to obtain written data, a base address, and transfer type information for specifying a storage unit for storing the written data. The counter is configured to count a frame synchronization pulse. The calculation circuit is configured to generate a chip select signal based on the transfer type information and the base address, as decoded by the decoder, and a count value of the frame synchronization pulse output by the counter.
