Usb to synchronous serial interface with external clock signal

An apparatus, comprising:

• a Universal Serial Bus (USB) port;
• a synchronous serial port;
• an application-specific integrated circuit (ASIC) that is configured to operate in a multi-protocol generic mode and in an adaptive clock mode, wherein the ASIC is configured to:
• implement a multi-protocol generic command processor in the multi-protocol generic mode where the ASIC is operable to be commanded so as to execute a generic data command that converts between a USB protocol and any commanded one of a plurality of synchronous serial protocols in the multi-protocol generic mode;
• execute the generic bus command to communicate a data payload between the USB port and the synchronous serial port by converting between the USB protocol and the commanded one of a plurality of synchronous serial protocols;
• and
• synchronize the execution of the generic bus command with an externally generated clock signal when the generic bus command is being implemented in accordance with the commanded one of the plurality of synchronous serial protocols.

A computer device, comprising:

• at least one memory configured to store computer executable instructions;
• and
• at least one processor operably associated with the at least one memory, wherein, when the at least one processor execute the computer executable instructions, the computer executable instructions cause the processor to:
• set an application-specific integrated circuit (ASIC) to operate in a multi-protocol generic mode and in an adaptive clock mode, wherein the ASIC is configured to execute a generic bus command that converts between a Universal Serial Bus (USB) protocol and any commanded one of a plurality of synchronous serial protocols in the multi-protocol generic mode;
• and
• issue the generic bus command to the ASIC in accordance with the commanded one of the plurality of synchronous serial protocols when the ASIC is set to operate in the multi-protocol generic mode and in the adaptive clock mode.
