Switching Characteristics over Commercial and Industrial Operating Ranges
Software Halt Cycle (25 MHz and 33 MHz)
Notes:
All timing parameters are measured at V
output test conditions are with C
a Testing is performed with equal loading on referenced pins.
b This parameter applies to the DEN signal.
