9.3.6.21 TX_INTERVAL_REG (Host mode only) Bit Definitions
| Bit Number | Name | Reset Value | Function |
|---|---|---|---|
| [7:0] | Tx Polling Interval/NAK Limit (m) | 0 | Defines the polling interval for the currently selected transmit endpoint for interrupt and ISO transfers. For bulk endpoints, this register sets the number of frames/microframes after which the endpoint should timeout on receiving a stream of NAK responses. There is one such register for each configured transmit endpoint (except endpoint 0). In each case the value that is set defines a number of frames/microframes (high speed transfers), as given in Table 9-44. |
