Which pins for the MAX6971

Other Hardware LEDs and Multiplexing
1

I was going to start out on the Arduino platform by messing around with an Arduino Nano (v3) and a Maxim MAX6971 to control some LED's. Looking at the basic diagram for the IC and the pinout for the Nano, it's pretty easy to see what connects to what except for two pins: The Latch (LE) and Enable (OE) connections. What pins would be best to connect LOAD and ENABLE to? I have V+ on the 5V pin, MOSI and MISO on D11 and D12 respectively, and CLK on D13. And suggestions for the other two connections?

From the data sheet:-

Output-Enable Input. High forces outputs OUT0 to OUT15 high impedance, without altering the contents of the output latches. Low enables outputs OUT0 to OUT15 to follow the state of the output latches.

so connect it to ground

and

Load-Enable Input. Data is loaded transparently from the internal shift register(s) to the output latch(es) while LE is high. Data is latched into the output latch(es) on LE’s falling edge, and retained while LE is low.

connect it to any pin and change it if you want.

Thanks! I'll try it.
