Systems and methods for serial communication |
摘要 |
This disclosure includes a point-to-point two-lineserial interface (TSI) suitable for use in a wireless communications device as well as in other applications. The TSI may employ a protocol providing multiple frame formats to achieve delivery of one type of message with a reduced latency and other messages at increased latencies. Further, although the master initiates reads, the slave circuit may signal the master in real time over the TSI. |

1. A method for communication between a master circuit and a slave circuit through a two-line interface including a first line and a second line, comprising:
biasing the first line to a first logical value when the first line is not being driven by the master circuit and is not being driven by the slave circuit; driving the second line at the first logical value by the master circuit; providing the slave circuit with control of the first line; driving a clock signal on the second line by the master circuit; driving a first sequence of bits on the first line by the master circuit; detecting the clock signal by the slave circuit; and sampling the first sequence of bits by the slave circuit. |
