Patent ID: 7856516

Claim:
A method for interfacing, without requiring changes to a burst transfer serial component, a single transfer serial component and the burst transfer serial component whose single transfer protocol and burst transfer protocol are incompatible, comprising: providing a buffer and a memory connected to the single transfer serial component while the burst transfer serial component remains unchanged, using at least one signal line from a peripheral device as input and interrupt source for handshaking, and providing no further hardware modifications; processing a completion of transfer of a byte from the burst transfer serial component to the single transfer serial component as an interrupt source event; maintaining the current state of at least one line corresponding to the interrupt source event to prevent occurrence of a next interrupt source event; reading the transferred byte from the buffer and copying the transferred byte to the memory; ceasing the maintaining of the current state of the at least one line corresponding to the interrupt source event to allow occurrence of the next interrupt source event; and enabling sending of a next byte from the burst transfer serial component.
