ALM_SYSRPHASE4

W0C

If high the sysrefphase4 state has been observed in the

sysrefalign logic at least once since the last sysrefalign sync.

ALM_SYSRPHASE3

W0C

If high the sysrefphase3 state has been observed in the

sysrefalign logic at least once since the last sysrefalign sync.

ALM_SYSRPHASE2

W0C

If high the sysrefphase2 state has been observed in the

sysrefalign logic at least once since the last sysrefalign sync.

ALM_SYSRPHASE1

W0C

If high the sysrefphase1 state has been observed in the

sysrefalign logic at least once since the last sysrefalign sync.

ALM_ALIGN_TO_R3

W0C

If high the align_to_r3 state has been observed in the sysrefalign

logic at least once since the last sysrefalign sync. TI Internal use

only.

ALM_ALIGN_TO_R1

W0C

If high the align_to_r1 state has been observed in the sysrefalign

logic at least once since the last sysrefalign sync. TI Internal use

only.

ALM_SD0_PLL

W0C

Driven high if the PLL in the Serdes 0 block goes out of lock. A

false alarm is generated at startup when the PLL is locking. User

will have to reset this bit after start to monitor accurately.

ALM_SD1_PLL

W0C

Driven high if the PLL in the Serdes 1 block goes out of lock. A

false alarm is generated at startup when the PLL is locking. User

will have to reset this bit after start to monitor accurately.

PLL_LOCK

W0C

Asserted when PLL is unlocked.
