Register block
Fields§
§tasks_startepin: [TASKS_STARTEPIN; 8]0x04..0x24 - Description collection[n]: Captures the EPIN[n].PTR and EPIN[n].MAXCNT registers values, and enables endpoint IN n to respond to traffic from host
tasks_startisoin: TASKS_STARTISOIN0x24 - Captures the ISOIN.PTR and ISOIN.MAXCNT registers values, and enables sending data on ISO endpoint
tasks_startepout: [TASKS_STARTEPOUT; 8]0x28..0x48 - Description collection[n]: Captures the EPOUT[n].PTR and EPOUT[n].MAXCNT registers values, and enables endpoint n to respond to traffic from host
tasks_startisoout: TASKS_STARTISOOUT0x48 - Captures the ISOOUT.PTR and ISOOUT.MAXCNT registers values, and enables receiving of data on ISO endpoint
tasks_ep0rcvout: TASKS_EP0RCVOUT0x4c - Allows OUT data stage on control endpoint 0
tasks_ep0status: TASKS_EP0STATUS0x50 - Allows status stage on control endpoint 0
tasks_ep0stall: TASKS_EP0STALL0x54 - Stalls data and status stage on control endpoint 0
tasks_dpdmdrive: TASKS_DPDMDRIVE0x58 - Forces D+ and D- lines into the state defined in the DPDMVALUE register
tasks_dpdmnodrive: TASKS_DPDMNODRIVE0x5c - Stops forcing D+ and D- lines into any state (USB engine takes control)
events_usbreset: EVENTS_USBRESET0x100 - Signals that a USB reset condition has been detected on USB lines
events_started: EVENTS_STARTED0x104 - Confirms that the EPIN[n].PTR and EPIN[n].MAXCNT, or EPOUT[n].PTR and EPOUT[n].MAXCNT registers have been captured on all endpoints reported in the EPSTATUS register
events_endepin: [EVENTS_ENDEPIN; 8]0x108..0x128 - Description collection[n]: The whole EPIN[n] buffer has been consumed. The RAM buffer can be accessed safely by software.
events_ep0datadone: EVENTS_EP0DATADONE0x128 - An acknowledged data transfer has taken place on the control endpoint
events_endisoin: EVENTS_ENDISOIN0x12c - The whole ISOIN buffer has been consumed. The RAM buffer can be accessed safely by software.
events_endepout: [EVENTS_ENDEPOUT; 8]0x130..0x150 - Description collection[n]: The whole EPOUT[n] buffer has been consumed. The RAM buffer can be accessed safely by software.
events_endisoout: EVENTS_ENDISOOUT0x150 - The whole ISOOUT buffer has been consumed. The RAM buffer can be accessed safely by software.
events_sof: EVENTS_SOF0x154 - Signals that a SOF (start of frame) condition has been detected on USB lines
events_usbevent: EVENTS_USBEVENT0x158 - An event or an error not covered by specific events has occurred. Check EVENTCAUSE register to find the cause.
events_ep0setup: EVENTS_EP0SETUP0x15c - A valid SETUP token has been received (and acknowledged) on the control endpoint
events_epdata: EVENTS_EPDATA0x160 - A data transfer has occurred on a data endpoint, indicated by the EPDATASTATUS register
shorts: SHORTS0x200 - Shortcut register
inten: INTEN0x300 - Enable or disable interrupt
intenset: INTENSET0x304 - Enable interrupt
intenclr: INTENCLR0x308 - Disable interrupt
eventcause: EVENTCAUSE0x400 - Details on what caused the USBEVENT event
halted: HALTED0x420..0x464 - Unspecified
epstatus: EPSTATUS0x468 - Provides information on which endpoint’s EasyDMA registers have been captured
epdatastatus: EPDATASTATUS0x46c - Provides information on which endpoint(s) an acknowledged data transfer has occurred (EPDATA event)

bmrequesttype: BMREQUESTTYPE0x480 - SETUP data, byte 0, bmRequestType
brequest: BREQUEST0x484 - SETUP data, byte 1, bRequest
wvaluel: WVALUEL0x488 - SETUP data, byte 2, LSB of wValue
wvalueh: WVALUEH0x48c - SETUP data, byte 3, MSB of wValue
