NOTES:
Notes 2, 6 and 14 are general and apply to all standard TTL signals used with the Pentium
1.
Not 100 percent tested. Guaranteed by design.
2.
TTL input test waveforms are assumed to be 0 to 3V transitions with 1V/nS rise and fall times.
3.
Non-test outputs and inputs are the normal output or input signals (besides TCK, TRST#, TDI, TDO, and TMS). These
timings correspond to the response of these signals due to boundary scan operations.
4.
APCHK#, FERR#, HLDA, IERR#, LOCK#, and PCHK# are glitch-free outputs. Glitch-free signals monotonically transition
without false transitions (i.e., glitches).
