5.1.6.22

Trigger Output Unit Control 3 Register

This register is indexed by the Trigger Unit Index Pointer value in bits [1:0] of the Global PTP Unit Index Register.

5.1.6.23

Trigger Output Unit Control 4 Register

This register is indexed by the Trigger Unit Index Pointer value in bits [1:0] of the Global PTP Unit Index Register.

5.1.6.24

Trigger Output Unit Control 5 Register

This register is indexed by the Trigger Unit Index Pointer value in bits [1:0] of the Global PTP Unit Index Register.

This register contains the PTP event trigger output PPS signal pulse width for unit 2 and path delay compensation for

unit 1.

Trigger Output Cycle or Bit Count (TRIGGER_CYCLE)

Defines the number of output cycles for generating periodic signals. It is

infinite if this field is zero.

0x0000

15:0

Trigger Output Bit Pattern (TRIGGER_BIT_PATTERN)

Defines the output bit pattern for generating output signals.

R/W

31:0

Trigger Output Iteration Cycle Time in Cascade Mode

(CASCADE_INTERATION_CYCLE_TIME)

Defines the iteration cycle time to go through all the trigger output units in

cascade mode. This time will be added to the current trigger target time for

the next trigger time. A unit value equals 1ns. For example, the cycle is

800ns if this field value is 800 (0x320).

23:16

PPS Pulse Width for Event Trigger (PPS_PULSE_WIDTH)

This field is the upper third byte (23:16) in conjunction with the trigger output

pulse width to make this to make this register value for PPS pulse width up to

124ms.

R/W

0x00

15:0

Trigger Output Pulse Width (TRIGGER_PULSE_WIDTH)

Defines the width for generating a pulse or periodic signal. Each unit value

equals 8ns. For example, the pulse width is 80ns if this register value is 10

(0xA).

R/W

0x0000
