Datasheet
14.2.5.221588 Configuration Register (1588_CONFIG)Offset: | 194h | Size: | 32 bits |
This read/write register is responsible for the configuration of the 1588 timestamps for all ports.
BITS | DESCRIPTION | TYPE | DEFAULT |
|
|
|
|
31 | Master/Slave Port 2 (M_nS_2) | R/W | 0b |
| When set, Port 2 is a time clock master and captures timestamps when a |
|
|
| Sync packet is transmitted and when a Delay_Req is received. When |
|
|
| cleared, Port 2 is a time clock slave and captures timestamps when a |
|
|
| Delay_Req packet is transmitted and when a Sync packet is received. |
|
|
|
|
|
|
30 | Primary MAC Address Enable Port 2 (MAC_PRI_EN_2) | R/W | 1b |
| This bit enables/disables the primary MAC address on Port 2. |
|
|
| 0: Disables primary MAC address on Port 2 |
|
|
| 1: Enables MAC address 01:00:5E:00:01:81 as a PTP address on Port 2 |
|
|
|
|
|
|
29 | Alternate MAC Address 1 Enable Port 2 (MAC_ALT1_EN_2) | R/W | 0b |
| This bit enables/disables the alternate MAC address 1 on Port 2. |
|
|
| 0: Disables alternate MAC address on Port 2 |
|
|
| 1: Enables MAC address 01:00:5E:00:01:82 as a PTP address on Port 2 |
|
|
|
|
|
|
28 | Alternate MAC Address 2 Enable Port 2 (MAC_ALT2_EN_2) | R/W | 0b |
| This bit enables/disables the alternate MAC address 2 on Port 2. |
|
|
| 0: Disables alternate MAC address on Port 2 |
|
|
| 1: Enables MAC address 01:00:5E:00:01:83 as a PTP address on Port 2 |
|
|
|
|
|
|
27 | Alternate MAC Address 3 Enable Port 2 (MAC_ALT3_EN_2) | R/W | 0b |
| This bit enables/disables the alternate MAC address 3 on Port 2. |
|
|
| 0: Disables alternate MAC address on Port 2 |
|
|
| 1: Enables MAC address 01:00:5E:00:01:84 as a PTP address on Port 2 |
|
|
|
|
|
|
26 | User Defined MAC Address Enable Port 2 (MAC_USER_EN_2) | R/W | 0b |
| This bit enables/disables the auxiliary MAC address on Port 2. The auxiliary |
|
|
| address is defined via the 1588_AUX_MAC_HI and 1588_AUX_MAC_LO |
|
|
| registers. |
|
|
| 0: Disables auxiliary MAC address on Port 2 |
|
|
| 1: Enables auxiliary MAC address as a PTP address on Port 2 |
|
|
|
|
|
|
25 | Lock Enable RX Port 2 (LOCK_RX_2) | R/W | 1b |
| This bit enables/disables the RX lock. This lock prevents a 1588 capture |
|
|
| from overwriting the Clock, UUDI and Sequence ID values if the 1588 RX |
|
|
| interrupt for Port 2 is already set due to a previous capture. |
|
|
| 0: Disables RX Port 2 Lock |
|
|
| 1: Enables RX Port 2 Lock |
|
|
|
|
|
|
24 | Lock Enable TX Port 2 (LOCK_TX_2) | R/W | 1b |
| This bit enables/disables the TX lock. This lock prevents a 1588 capture |
|
|
| from overwriting the Clock, UUDI and Sequence ID values if the 1588 TX |
|
|
| interrupt for Port 2 is already set due to a previous capture. |
|
|
| 0: Disables TX Port 2 Lock |
|
|
| 1: Enables TX Port 2 Lock |
