This read only register combined with the 1588 Port x TX Egress Time NanoSeconds Register (1588_TX-
_EGRESS_NS_x) contains the TX timestamp captures. Up to four captures are buffered.
Note: Values are only valid if the 1588 TX Timestamp Count (1588_TX_TS_CNT[2:0]) field indicates that at least
one timestamp is available.
Note:
Port and GPIO registers share a common address space. Port registers are selected by the Bank Select
(BANK_SEL[2:0] in the 1588 Bank Port GPIO Select Register (1588_BANK_PORT_GPIO_SEL). The port
accessed (“x”) is set by the Port Select (PORT_SEL[1:0]) field.
