45.2.1.192.1 PMAIPMD reset (1 .2309.15)
Resetting the Mu1tiGBASE-Tl PMA/PMD is accomplished by setting bit 1.2309.15 to a one. This action shall set all PMA/PMD registers to their default states. As a consequence, this action may change the internal state of a Mu1tiGBASE-T1 PMA/PMD and the state of the physical link. This action may also initiate a reset in any other MMDs that are instantiated in the same package. Bit 1.2309.15 is self-clearing. and the Mu1tiGBASE-T1 PMA/PMD shall return a value of one in bit 1.2309.15 when a reset is in progress; otherwise, it shall return a value of zero. The MuItiGBASE-T1 PMA/PMD is not required to accept a write transaction to any of its registers until the reset process is completed. The control and management interface shall be restored to operation as defined in 149.4.2.1, starting when bit 1.2309.15 is set.
During a reset, the Mu1tiGBASE-T1 PMA/PMD shall respond to reads from register bits 1.2309.15,
1.8.15:14, and 1.0.15. All other register bits shall be ignored.
NOTE—This operation may interrupt data communication.
Bit 1.2309.15 is a copy of bit 1.0.15 and setting or clearing either bit shall set or clear the other bit. Setting either bit shall reset the MuItiGBASE-TI PMA/PMD.
45.2.1.192.2 Transmit disable (1 .2309.14)
When bit 1.2309. 14 is set to a one, the PMA shall disable output on the transmit path. When bit 1.2309.14 is set to a zero, the PMA shall enable output on the transmit path.
Bit 1.2309.14 is a copy of bit l.9.() and setting or clearing either bit shall set or clear the other hit. Setting either bit shall disable the transmitter.
45.2.1.192.3 Low power (1 .2309.11)
When the low-power ability is supported, the Mu1tiGBASE-T1 PMA/PMD may be placed into a low-power mode by setting bit 1.2309.11 to one. This action may also initiate a low-power mode in any other MMDs that are instantiated in the same package. The low-power mode is exited by resetting the MuItiGBASE-Tl PMA/PMD. The behavior of the Mu1tiGBASE-T1 PMA!PMD in transition to and from the low-power mode is implementation specific and any interface signals should not be relied upon. While in the low-power mode, the device shall, at a minimum, respond to management transactions necessary to exit the low-power mode. The default value of bit 1 .2309.11 is zero. This operation interrupts data communication. Bit 1.2309.11 isa copy ofbit 1 .0.11 and setting or clearing either bit shall set or clear the other bit. Setting either bit shall put the MultiGBASE-T1 PMAPMD in low-power mode.
45.2.1.193.1 MultiGBASE-T1 OAM ability (1.2310.11) When read as a one, bit 1.2310.11 indicates that the MultiGBASE-TI PHY supports MultiGBASE-T1 OAM (see 149.3.9). When read as a zero, bit 1.2310.11 indicates that the MultiGBASE-T1 PHY does not support MultiGBASE-TI OAM. 45.2.1.193.2 EEE ability (1.2310.10) When read as a one, bit 1.2310.10 indicates that the MultiGBASE-T1 PHY supports EEE. When read as a zero, bit 1.23 10.10 indicates that the MultiGBASE-T1 PHY does not support EEE. 45.2.1.193.3 Receive fault ability (1.2310.9) When read as a one, bit 1.2310.9 indicates that the MultiGBASE-T1 PMA/PMD has the ability to detect a fault condition on the receive path. When read as a zero, bit 1.2310.9 indicates that the MultiGBASE-T1 PMAPMD does not have the ability to detect a fault condition on the receive path. 45.2.1.193.4 Low-power ability (1.2310.8) When read as a one, bit 1.2310.8 indicates that the MultiGBASE-T1 PMA/PMD supports the low-power feature. When read as a zero, bit 1.23 10.8 indicates that the MultiGBASE-T1 PMA/PMD does not support the low-power feature. If the MultiGBASE-T1 PMA/PMD supports the low-power feature, then it is controlled using either bit 1.2309.11 orbit 1.0.11.IEEE Std 802.3ch pdf download.
