Bit
Default
—
0x40A—IMA_LNK_DIFF_DEL (IMA Link Differential Delay Write Counter)
Link Delay Write
Counter
This register, along with bit 5 of address 0x409, reports the value of the SRAM write
phase at the time when the read phase is 0. This phase information is used to calculate
the link differential delay.

This field contains a snapshot of 8 of the least significant bits of the SRAM write
counter for the diagnostic link (selected using address 0x409).
All others (Range: 0x00–0xFF)
Delay Window = 0 (see register 0x415): Value = Cell_count >> 1
Delay Window = 1–3 (see register 0x415): Value = Cell_count
Delay Window = 4 (see register 0x415): Value = Cell_count >> 2
