DESCRIPTION
Comma indication for the current latency measurement. Cleared when
Register 0x12 is read

Latency measurement ready indicator
0 = Indicates latency measurement not complete.
1 = Indicates latency measurement is complete and value in latency
measurement counter (LATENCY_MEAS_COUNT[19:0]) is ready to be read.
Bits[19:16] of 20 bit wide latency measurement counter.
Latency measurement counter value represents the latency in number of clock
cycles. This counter will return 20’h00000 if it is read before rx comma is
received. If latency is more than 20’hFFFFF clock cycles then this counter
returns 20’hFFFFF.
COR ⁽¹⁾
(1) User has to make sure Register 0x11 has to be read first before reading Register 0x12. Latency measurement counter value resets to
20’h00000 when Register 0x12 is read. Comma indication (17.15 and 17.14) and count valid (17.4) bits are also cleared when Register
0x12 is read.
