Synchronous card operation is broken down into three primary types. These are commonly referred to as
2-wire, 3-wire and I2C synchronous cards. Each card type requires different control and timing and
therefore requires different algorithms to access. Teridian has created an application note to provide
detailed algorithms for each card type. Refer to the application note titled 73S12xxF Synchronous Card
