Abstract: Certain aspects of the present disclosure provide an apparatus for wireless communication. The apparatus generally includes a plurality of slave radio frequency (RF) devices, a master RF device configured to set a configuration parameter in a register to be applied by an RF slave device of the plurality of RF slave devices, and a clock line coupled between the master RF device and the plurality of slave RF devices. The slave RF device may be configured to: count a number of cycles of a clock signal on the clock line; and apply the configuration parameter for the slave RF device based on the count of the number of cycles, wherein the master RF device is further configured to disable an interrupt reporting function of the plurality of slave RF device during a time period between setting the configuration parameter in the register and the configuration parameter being applied.

Abstract: Systems and methods for variable stride counting for timed-triggers in a radio frequency front end (RFFE) bus modify how a master clock controls counters in slaves. In particular, instead of having the master clock change a counter at a slave device on a one-to-one clock tick-to-counter change, exemplary aspects of the present disclosure contemplate allowing a bus ownership master (BOM) to select a stride size wherein each clock tick causes the counter to change by the size of the stride. Clock ticks are then sent less frequently over the clock line of the RFFE bus. In this fashion, fewer clock ticks are required to change the counter to the trigger event.
