Timestamp Control and Status Register

Fields in this register are indexed by the Trigger Unit Index Pointer (bits [1:0]), Timestamp Unit Index Pointer (bit 8), and

GPIO Index Pointer (bit 16) 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

Note:

This field is indexed by the GPIO Index Pointer (bit 16) value in the

Global PTP Unit Index Register.

R/W

GPIO Inputs Monitor (GPIO_IN)

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

Note:

This field is indexed by the GPIO Index Pointer (bit 16) value in the

Global PTP Unit Index Register.

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)

Note:

This field is indexed by the GPIO Index Pointer (bit 16) value in the

Global PTP Unit Index Register.

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.
