DP83867IR: 100Base-TX transmit latency

Hello,

It appears that these settings are geared towards bringing down the receive latency, not transmit latency. We don't expect any side effect with these configurations. Are you seeing any functional issues?

Sincerely,

Gerome

Hi Gerome,

Thank you for your answer. So below description might be updated because it sounds this bit affects transimit latency.

6.4 LOW_LATENCY_10_100_EN

Configuration Configuration of LOW_LATENCY_10_100_EN is only applicable to 10/100 operation. When configured, the transmit latency is reduced by one clock cycle

Regarding side effect, there is no specfic issues so far. Understood that expecting no side effect.

Hi Gerome,

I have one more question. In my understanding, below application note covers all DP83867 despite of the suffix.

Importance of Latency in Factory Automation (Rev. A)

Is this understanding correct? This is because there is no information for LOW_LATENCY_10_100_EN bit on the DP83867IR datasheet.

I need your confirmation if DP83867IR supports this bit.
