Reset Description
0x0000.0
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
0x0
Timestamp Interrupt Status
This bit is cleared by reading the TSSOVF bit in the MAC timestamp
Status Register (EMACTIMSTAT) register.
In this mode, this bit is cleared after the completion of the read of this
bit. In all other modes, this bit is reserved.
Value Description
0 No timestamp interrupt is present.
1 When the advanced timestamp feature is enabled, this bit
indicates one of two conditions is true:
■ The system time value equals or exceeds the value
specified in the EMAC Target Time Seconds Register
(EMACTARGSEC) and MAC Target Time Nanoseconds
(EMACTARGNANO) registers.
■ There is an overflow in the EMAC Target Time Seconds
(EMACTARGSEC) register.
When default timestamping is enabled, this bit indicates that
the system time value is equal to or exceeds the value specified
in the EMAC Target Time registers. In this mode, this bit is
cleared after the completion of the read of this bit.
