This is a read-only register. However, during the

programming of the Unique Slave Identifier

(USID), a write command sequence is performed

on this register but the value is not changed.

Note 4: Unlike the complete independence between triggers 0, 1, and 2, and also between the associated trigger masks 0, 1, and 2,

respectively, as described in the MIPI RFFE Specification, this device uses additional interactions between the provided trigger functions.

The delayed application of updated data to all triggerable registers in this device may be accomplished using any of the three triggers (0,

1, or 2), provided that the particular trigger used is not currently masked off. If multiple triggers are enabled, any or all of those are

sufficient to cause the data to be transferred from shadow registers to destination registers for all triggerable registers in the device. It is

also necessary to disable all three triggers (i.e., set all three trigger masks) to ensure that data written to any triggerable register will

immediately be written to the destination register at the conclusion of the RFFE command sequence where the data is written.
