Configuring I/O Port Directions
The direction of each I/O port is configured using shared pins PGS2 - 0. For detailed information, see the
section on Configuration Using Shared Pins.
Open-Drain Mode
Either push-pull or open-drain output type is configurable for ports A, B, and C through the network using
PAOD, PBOD, and PCOD. For detailed information, see the section on Configuration Through Network.
Initializing OUTPUT PORTs
OUTPUT PORTs are initialized to high-impedance by the following events:
The data from the OUTPUT DATA packet are outputted to the corresponding port again when the
OUTPUT DATA packet is received.
Switching Timing In OUTPUT PORTs
To prevent simultaneously switching OUTPUT PORTs which would generate noise, a time delay is
provided for each group ports. The delay time depends on the input clock: 50 ns at 20 MHz clock. The
figure below shows timing relationships between the OUTPUT PORT and the output strobe flag, nPOSTR.
Node dropped from network (EMGYMD = 1; MYRECON asserted)
For detailed information, see EMGYMD in the section on Configuration Through Network.
The INITIALIZE OUTPUT PORT command is received
Hardware reset
The SOFTWARE RESET command is received
