Note:
*1: Typical values are not guaranteed. The values listed are tested at room temperature and based on
a limited number of samples.
*2: Pins of ports 1~4 source a transition current when they are being externally driven from 1 to 0.
The transition current reaches its maximum value when V_IN is approximately 2V.
*3: Under steady state (non-transient) conditions, I_OL must be externally limited as follows:
Maximum I_OL per port pin: 20mA
Maximum I_OL per 8-bit port: 40mA
Maximum total I_OL for all outputs: 100mA
*4: If I_OH exceeds the test condition, V_OH will be lower than the listed specification.
If I_OL exceeds the test condition, V_OL will be higher than the listed specification.
*5: Tested while CPU is kept in reset state and EA=H, Port0=H.

21.3 AC CHARACTERISTICS
The AC specifications are a function of the particular process used to manufacture the part, the ratings
of the I/O buffers, the capacitive load, and the internal routing capacitance. Most of the specifications
can be expressed in terms of multiple input clock periods (TCP), and actual parts will usually experi-
ence less than a ±20 nS variation. The numbers below represent the performance expected from a 0.6
micron CMOS process when using 2 and 4 mA output buffers.
