SWITCHING CHARACTERISTICS over COMMERCIAL operating range
Ready and Peripheral Timing (33 MHz and 40 MHz)
Notes:
All timing parameters are measured at 1.5 V with 50 pF loading on CLKOUTA unless otherwise noted. All output test conditions
are with C
a This timing must be met to guarantee proper operation.
b This timing must be met to guarantee recognition at the clock edge.
