5.1.6.16

GPIO Status Monitor 1 Register

This register provides the interrupt status for the trigger output unit and timestamp units used with the GPIO. The GPIO

pin Output Trigger and Timestamp Unit interrupt status bit in the Global Interrupt Status Register is the OR of the status

bits in this register.

2:0

Event Trigger Output Unit Done (TRIGGER_DONE)

(Bit 2 = Trigger Unit 2, Bit 1 = Trigger Unit 1, Bit 0 = Trigger Unit 0)

1 = The event trigger output unit has been generated when the TRIG-

GER_NOTIFY bit is set to “1” in the Trigger Output Unit Control 1 Register

(write “1” to clear this bit) and will generate an interrupt to the host.

0 = Event trigger output unit not done.

Trigger Output Unit Interrupt Status

(Bit 18 = Trigger Unit 2, Bit 17 = Trigger Unit 1, Bit 16 = Trigger Unit 0)

These three bits provide the interrupt status for the three Trigger Output

Units. These interrupts are enabled by setting the TRIGGER_NOTIFY bit in

the Trigger Output Unit Control 1 Register. This is done separately for each

TOU. Refer to the GPIO Status Monitor 0 Register for the Trigger Output Unit

status details.

1 = Interrupt detected

0 = No interrupt

Timestamp Unit Interrupt Status (GPIO input timestamp only)

(Bit 1 = Timestamp Unit 1, Bit 0 = Timestamp Unit 0)

These two bits provide the interrupt status for the two Timestamp Output

Units for the GPIO. These interrupts are enabled by the Timestamp Unit

Interrupt Enable bit in the Timestamp Control and Status Register. This is

done separately for each TSU. Refer to the registers beginning at the

Timestamp Status and Control Register for Timestamp interrupt details.

For the interrupt status for the port-based timestamping of PTP egress

frames, refer to the Port Interrupt Status Register and Port PTP Timestamp

Interrupt Status Register.

1 = Interrupt detected

0 = No interrupt
