Timestamp Control and Status Register

Portions of this register are indexed by the Trigger Unit Index Pointer (bits [1:0]) and Timestamp Unit Index Pointer (bit

8) values in the Global PTP Unit Index Register.

Address:

0x052C - 0x052F

Size:

32 bits

GPIO Output Source Select (GPIO_OUT_SEL)

1 = The output is a combinatorial result

0 = The output is from flopped output

R/W

GPIO Inputs Monitor (GPIO_IN)

This field reflects the current value seen on the GPIO input.

R-

GPIO Output Enable (GPIO_OEN)

1 = Enables the GPIO pin as a timestamp input

0 = Enables the GPIO pin as a trigger output (default)

R/W

Timestamp Unit Interrupt Enable (TS_INT_ENB)

The timestamp unit interrupt status bit is found in the GPIO Status Monitor 1

0 = Interrupt disabled

1 = Interrupt enabled

Note:

This field is indexed by the Timestamp Unit Index Pointer (bit 8)

value in the Global PTP Unit Index Register.

R/W

Event Trigger Output Unit Active (TRIGGER_ACTIVE)

1 = The event trigger output unit is enabled and active without error

0 = The event trigger output unit is finished and inactive

Note:

This field is indexed by the Trigger Unit Index Pointer (bits 1:0)

value in the Global PTP Unit Index Register.

R0b

Event Trigger Output Unit Enable (TRIGGER_EN)

1 = Enables the selected event trigger output unit. Self-clearing when trigger

output is generated. In cascade mode, only enable the head of the trigger unit.

0 = The event trigger out unit is disabled

Note:

This field is indexed by the Trigger Unit Index Pointer (bits 1:0)

value in the Global PTP Unit Index Register.

R/W

Event Trigger Output Unit Software Reset (TRIGGER_SW_RESET)

1 = Resets the trigger output unit to the inactive state and default settings.

This reset can be used to stop the cascade mode in continuous operation and

prepare this trigger unit for the next operation.

0 = Trigger output unit under normal operation

Note:

This field is indexed by the Trigger Unit Index Pointer (bits 1:0)

value in the Global PTP Unit Index Register.

R/W

Event Timestamp Input Unit Enable (TS_ENB)

1 = Enables the selected event timestamp input unit. Writing “1” to this bit will

clear the TS_EVENT_DET_CNT of the associated unit.

0 = Disables the selected event timestamp input unit. Writing “0” to this bit will

clear the TS_RDY and TS_DET_CNT_OVFL.

Note:

This field is indexed by the Timestamp Unit Index Pointer (bit 8)

value in the Global PTP Unit Index Register.
