Programmable Registers
26.4.94 ENET MAC IEEE1588 Timestamp of the last Frame Register
Timestamp of the last Frame transmitted by the controller that had the ff_tx_ts_frm signal
asserted from the user application. Valid when the Interrupt status bit TS_AVAIL is set to
'1'.

Reserved bits. Write as 0.
Correction increment value. This value will be added every time the correction timer expires (every clock
cycles given in ATIME_CORR).
A value smaller than in bits 6:0 will slow down the timer. A value larger than in bits 6:0 will speed up the
timer.
Reserved bits. Write as 0.
Clock period of the timestamping clock (ts_clk) in nanoseconds. The timer will increment by this amount
with every clock cycle. For example, 10 for 100MHz, 8 for 125MHz, 5 for 200MHz.
