5.1.6.14

Global PTP Unit Index Register

This register is used to index the timestamp unit and trigger unit for accesses to PTP registers in the address range of

0x052C to 0x05B3. The timestamp and trigger units selected in this register will be the units that are read/written when

accessing these registers.

5.1.6.15

GPIO Status Monitor 0 Register

7:0

PTP Domain

This is the value of the PTP message domain number field. If domain

checking is enabled (Global PTP Message Config 2 Register, bit 4), the

timestamp capture will be enabled when the receive PTP message domain

number matches the value in this field. If domain checking is not enabled,

the domain number field will be ignored.

Event Trigger Output Error (TRIGGER_ERROR)

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

1 = The event trigger time is set earlier than the system time clock when the

TRIGGER_NOTIFY bit is set to “1” in the Trigger Output Unit Control 1 Regis-

ter and will generate an interrupt to the host. This bit can be cleared by reset-

ting the TRIGGER_EN bit to “0” in the Timestamp Control and Status

0 = No event trigger error.
