9.3.6.20 NAK_LIMIT0_REG (Hots mode only) Bit Definitions
| Bit Number | Name | Reset Value | Function |
|---|---|---|---|
| [4:0] | Endpoint0 NAK Limit (m) | 0 | Sets the number of frames/microframes
(high-speed transfers) after which endpoint 0 should timeout on receiving a
stream of NAK responses. Equivalent settings for other endpoints can be made
through their TX_INTERVAL_REG and TX_INTERVAL_REG registers. The number of frames/microframes selected is 2(m – 1) (where, m is the value set in the register, valid values are 2 – 16). If the host receives NAK responses from the target for more frames than the number represented by the limit set in this register, the endpoint will be halted. A value of 0 or 1 disables the NAK timeout function. |
