Abstract
A signal transceiving device includes a first controller and a second controller. The first controller is configured to transmit transmission data. The second controller is coupled to the first controller by a plurality of interrupt signal wires and a data transmission bus. Wherein the second controller respectively transmits a plurality of interrupt signals to the first controller through the plurality of interrupt signal wires, and the first controller determines a size of the transmission data according to the interrupt signals.
Claims13
A signal transceiving device, comprising:
- a first controller, being configured to transmit transmission data;
- a second controller, coupled to the first controller by a plurality of interrupt signal wires and a data transmission bus,
- wherein the second controller is configured to respectively transmit a plurality of interrupt signals to the first controller through the plurality of interrupt signal wires, and the first controller is configured to determine a size of the transmission data according to the interrupt signals, wherein the first controller is further configured to:
- determine the size of the transmission data is a first size if only a transition edge of a first interrupt signal of the interrupt signals is detected;
- determine the size of the transmission data is a second size if only a transition edge of a second interrupt signal of the interrupt signals is detected;
- and
- determine the size of the transmission data is a third size if both of the transition edges of the first interrupt signal and the second interrupt signal of the interrupt signals are detected.
