# Hex Digit Display

Library: | Input/Output
Introduced: | 2.2.0
Appearance: |

## Behavior

Using a seven-segment display, shows the hexadecimal digit corresponding to the four-bit input. If any of the inputs are not 0/1 (either floating or error), then the display shows a dash ('-'). A separate one-bit input controls the display of the decimal point.

## Pins

South edge, first from left (input, bit width 4)
  This input is interpreted as an unsigned four-bit number, and the corresponding hexadecimal digit is displayed. If any of the bits are floating or error, then a dash ('-') is displayed.
South edge, second from left (input, bit width 1)
  Controls the decimal point. If this is left unconnected, the decimal point remains off.
