Question: On the SA-1110, GPIO 26 has an alternate function that outputs the internal clock/2. Can software switch between the alternate function for pin 26 and a dedicated output to use this as a clock gating feature?

Resolution: RCLK_OUT on GPIO26 began as a test function so that proper operation of the PLL could be tested. Its function was then made public so that customers could use it as an external clock. It is not specified for gated operation. That part of the device is not likely to see a lot of changes, so there is a good chance that behavior is consistent over time and changes in stepping.

This info is from Intel devloper Q&A...

pin... GPIO26 was an experment for the PLL.....``The various clocks available through GPIO27 are less useful`` and ``The ring oscillators are not very accurate and have no relation to the core clock.``

So what`s the deal ?...lol

passed on from ARM....Intel follows a set protocol....I`d like ARM to have the problem ...lol
