| DESCRIPTION | TYPE | DEFAULT |
|
|
|
| |
3 | 1588 Port 0(Host MAC) TX Interrupt (1588_MII_TX_INT) | R/WC | 0b | |
| This interrupt indicates that a packet from the Host MAC to the switch fabric |
|
| |
| matches the configured PTP packet and the 1588 clock was captured. |
|
| |
| Note: | For Port 0, receive is defined as data from the switch fabric, while |
|
|
|
| transmit is to the switch fabric. |
|
|
|
|
|
| |
2 | 1588 GPIO9 Interrupt (1588_GPIO9_INT) | R/WC | 0b | |
| This interrupt indicates that an event on GPIO9 occurred and the 1588 clock |
|
| |
| was captured. These interrupts are configured through the General Purpose |
|
| |
| I/O Configuration Register (GPIO_CFG) register. |
|
| |
| Note: | As 1588 capture inputs, GPIO inputs are edge sensitive and must |
|
|
|
| be active for greater than 40 nS to be recognized as interrupt |
|
|
|
| inputs. |
|
|
|
|
|
| |
1 | 1588 GPIO8 Interrupt (1588_GPIO8_INT) | R/WC | 0b | |
| This interrupt indicates that an event on GPIO8 occurred and the 1588 clock |
|
| |
| was captured. These interrupts are configured through the General Purpose |
|
| |
| I/O Configuration Register (GPIO_CFG) register. |
|
| |
| Note: | As 1588 capture inputs, GPIO inputs are edge sensitive and must |
|
|
|
| be active for greater than 40 nS to be recognized as interrupt |
|
|
|
| inputs. |
|
|
|
|
|
| |
0 | 1588 Timer Interrupt (1588_TIMER_INT) | R/WC | 0b | |
| This interrupt indicates that the 1588 clock equaled or passed the Clock |
|
| |
| Target value in the 1588 Clock Target |
|
| |
| (1588_CLOCK_TARGET_HI) and 1588 Clock Target |
|
| |
|
|
| ||
| Note: | This bit is also cleared by an active edge on GPIO[9:8] if enabled. |
|
|
|
| For the clear function, GPIO inputs are edge sensitive and must be |
|
|
|
| active for greater than 40 nS to be recognized as a clear input. |
|
|
|
| Refer to Section 13.2, "GPIO Operation," on page 162 for |
|
|
|
| additional information. |
