12/130

Notes : 1. D0/15 input/output pins must be connected to one single external pull up resistor if not used.

I.1 - Pin Definition

The pins of the circuit are five volts tolerant except

the pins assigned to SDRAM interface.

I.1.1 - Input Pin Definition

I.1.2 - Output Pin Definition

Moreover, each output is high impedance when the NTEST Pin is at 0 volt.
