Background
Asynchronous interfaces, such as IIC, SPI, UART, are a common way of interface communication for slave devices. When a master device wants to communicate with a slave device using a specific communication method, a specific communication protocol needs to be satisfied: the selection of the communication protocol is typically accomplished using a specific pin to either a logic high level or a logic low level, or the master device sends a specific sequence of signals. To select a communication protocol, the pins of the chip are typically consumed, or a specific sequence needs to be sent before the formal communication, or a specific communication protocol is implemented by a configuration register. The above approach would undoubtedly consume redundant pins, or increase the complexity of communication, reducing software portability. Accordingly, an automatic detection apparatus and method that occupies a reduced pin count and simplifies the implementation of communications is desired.
