Peripheral Simulation

For Atmel AT89C5130 — Port 4 (2-bit)

Simulation support for this peripheral or feature is comprised of:

These simulation capabilities are described below.

Parallel Port 4

This dialog displays the SFR and pins of Port 4.

P4: This is the P4 SFR. The HEX value and value of each bit is displayed and may be changed from this dialog.
Pins: These are the states of the pins on the simulated MCU. When used as outputs, these have the same value as the P4 SFR. When used as inputs (P4.x is 1) you may set the level of the input pin to high (1) or low (0).
