26.6.13 MAC Interrupt mask register
The Interrupt Mask Register bits enables the user to mask the interrupt signal due to the
corresponding event in the Interrupt Status Register.
26.6.14 MAC Address 0 high register
The MAC Address 0 High register holds the upper 16 bits of the 6-byte first MAC address
of the station. Note that the first DA byte that is received on the MII interface corresponds
to the LS Byte (Bits [7:0]) of the MAC Address Low register. For example, if
0x112233445566 is received (0x11 is the first byte) on the MII as the destination address,
then the MacAddress0 Register [47:0] is compared with 0x665544332211.

Timestamp interrupt status
When Advanced Timestamp feature is enabled, this bit is
set when any of the following conditions is true:
• The system time value equals or exceeds the value
specified in the Target Time High and Low registers
• There is an overflow in the seconds register
This bit is cleared on reading the byte 0 of the Timestamp
Status register (
Otherwise, when default Time stamping is enabled, this bit
when set indicates that the system time value equals or
exceeds the value specified in the Target Time registers. In
this mode, this bit is cleared after the completion of the read
of this Interrupt Status Register[9]. In all other modes, this
bit is reserved.
