PROGRAMMED DELAY FOR RFFE BUS TRIGGERS
First Claim
1. A method of data communications, comprising:
- receiving trigger configuration information in a first transaction conducted over a serial bus;
receiving a trigger actuation command from a bus master coupled to the serial bus;
delaying a trigger actuation signal for a delay duration defined by the trigger configuration information, wherein the trigger actuation signal is generated in response to the trigger actuation command; and
providing the trigger actuation signal after the delay duration has expired.

Abstract
Systems, methods, and apparatus for improving bus latency are described. A data communication apparatus has an interface circuit adapted to couple the apparatus to a first serial bus, a clock source configured to provide a clock signal and a trigger handler. The interface circuit may be configured to receive trigger configuration information in a first transaction conducted over a serial bus, and receive a trigger actuation command from a bus master coupled to the serial bus. The trigger handler may be configured to delay a trigger actuation signal for a delay duration defined by the trigger configuration information, and provide the trigger actuation signal after the delay duration has expired. The trigger actuation signal may be generated in response to the trigger actuation command.

15. A method of data communications, comprising:
-
transmitting trigger configuration information in a first transaction conducted over a serial bus; and transmitting a trigger actuation command to at least one slave device coupled to the serial bus, wherein the trigger configuration information defines a delay duration used by the at least one slave device to delay one or more trigger actuation signals generated by the at least one slave device in response to the trigger actuation command. - View Dependent Claims (16, 17, 18, 19, 20)
