21.9.3 USB main processing

Sep 30, 2010
USB main processing involves processing USB transactions. The types of transactions to be processed are as follows.
• Fully automatically processed request for control transfer
• Automatically processed requests for control transfer
• CPUDEC request for control transfer
• Processing for bulk transfer (IN)
• Processing for bulk transfer (OUT)
• Processing for interrupt transfer (IN)
Processing for endpoint n involves writing or reading for data transfer. The flowchart shown below is for PIO.
(1) Fully automatically processed request for control transfer
(2) Automatically processed requests for control transfer
(SET_CONFIGURATION, SET_INTERFACE, SET_FEATURE, CLEAR_FEATURE)
Because the fully automatically processed request for control transfer is executed by hardware, it cannot be
referenced by FW. Therefore, FW does not have to perform any special processing for this request.
(SET_CONFIGURATION, SET_INTERFACE, SET_FEATURE, CLEAR_FEATURE)
Processing to write a register for automatically processed requests for control transfer, such as
SET_CONFIGURATION, SET_INTERFACE, SET_FEATURE, and CLEAR_FEATURE requests, is automatically
executed by hardware, but an interrupt request is issued for recognition on the device side. This processing may be
ignored if there is no special processing to be executed.
The flowcharts are shown below.
