VLOAD
VOH – 0.15 V
VOL + 0.15 V
For timing purposes, a port pin is no longer floating when a
150 mV change from load voltage occurs and begins to float
when a 150 mV change from the loading VOH/VOL level occurs
with IOL/IOH ≤15 mA.

EXPLANATION OF AC SYMBOLS
Each AC timing symbol is two pairs of letters prefixed by “T” for time. The characters in a pair indicate a signal
and its condition, respectively. Symbols represent the time between the two signal/condition points.
