1. Insertion delays are specified from XTAL2. These delays are more meaningful because the XTAL1-to-XTAL2 delay is sensi-
AT94K Series FPSLIC
tive to system loading on XTAL2. If it is necessary to drive external devices with the system clock, devices should use
XTAL2 output pin. Remember that XTAL2 is inverted in comparison to XTAL1.
