Field Documentation

uint8_t* data

Holds address of data buffer. It represents source buffer for OUT or SETUP transfer and destination address for IN transfer

uint16_t ep_max_packet_size

Maximum packet size for the selected pipe

uint8_t ep_type

Endpoint type for selected pipe

uint8_t event

Holds pipe specific event flags

uint8_t in_use

Set to true when transfer is in progress and reset only after the /ref num of bytes is transferred

uint8_t interrupt_triggered

For INTERRUPT or ISOCHRONOUS pipe, indicates if retransmit timeout has occurred

uint16_t interval

For INTERRUPT or ISOCHRONOUS pipe, it represents the decrementing count to reach 0 for initiating retransmission

uint16_t interval_reload

For INTERRUPT or ISOCHRONOUS pipe, it represents the period for repeated transfer

uint32_t num

Number of bytes of data to be transmitted

uint32_t num_transferred_total

Number of bytes transmitted or received at the moment

uint32_t num_transferring

Number of bytes being transmitted currently

uint32_t packet

Holds packet token and PID information of ongoing data packet transaction

uint8_t transfer_active

Set to true when a transfer has been initiated and reset when event for transfer complete occurs
