Clocking During Test | Intel SA-1100 manual

Clocks

If the PXTAL or TXTAL pin is driven above the voltage indicated, there will be no permanent damage to the processor for pin voltages less than 2.5 V. However, ESD diodes on these pins will attempt to clamp the voltage at approximately 1.5 V. The clamping action results in significant noise injected into an internally generated supply used by several sensitive circuits on the processor. Consequently, driving this pin higher than the 1 V limit can result in unpredictable operation not obviously connected with the crystal pins. Users should refrain from driving the crystal pins higher than 1 V even if there is no obvious side effect.

Note: In every system, there must be a provision for both a 3.6864-MHz and a 32.768-kHz source either from an external oscillator or a crystal.

8.4Clocking During Test

If TCK_BYP is high, then the PLLs and oscillators are not used and the high-speed core clock is supplied externally on the TESTCLK pin. This mode is for testing only and is not supported for standard operation.
