The 82C55 may be programmed to operate in Input/Ouput (mode 0), Strobed Input/Ouput (mode 1) or Bi-Directional Bus (mode 2). The following information describes mode 0 operation. Users needing information regarding other modes of operation should refer to an Intel or Intersil 82C55 data sheet.

Upon power-up, an 82C55 is reset and defaults to the input mode. No further programming is needed to use the 24 lines of an 82C55 as TTL inputs.
