Other Parts Discussed in Thread: C2000WARE
Tool/software:
Section 32.3.11 of the 'F2838x TRM [spruii0e] describes a feature of the FSI receiver core for which register definitions for configuration of said feature are missing from both the TRM and the C2000ware bitfield and driverlib implementations.
Aforementioned section describes the FSI RX module's ability to assert receiver module trigger event signals in response to one of several selectable events (such as data frame tag match).
Through figure 32-14 and table 32-11 in the TRM, we are advised that the FSI RX module embodies registers so named "RX_TRIG_CTRL_n" (where n may be 0-3) which presumably embody fields for control of behavior of corresponding event signals RX_TRIG_n.
It is naturally of great disappointment when we find registers by such names neither expounded in section 32.6 of the TRM, nor laid out in even the latest C2000ware support libraries (v5.02.00.00) for this device family, attached.
There is very limited information about these signals, although through TI's own material [spruiw4] for the 'F28003, we find reference to said register names in Table 3-1 of section 3.2 of that document.
We wish to utilize these receiver core event signals for either triggering (capture event) or synchronizing (counter reset event) the eCAP in order to affect a clock alignment scheme in a multi-node control platform employing an FSI star topology. That is, the broadcast of a particular frame by the master node which slave nodes observe with matching frame tag asserts a RX_TRIG event to capture or sync their eCAP (for example, as expounded on page 2855 of the TRM for ECAPSYNCINSEL.SEL for selection value 1F which highlights selection FSI_RXA_RX_TRIG1) which can be sent back to the master for comparison and transmission of counter adjustments. Such configuration appears not possible without correct expounding of the aforementioned RX_TRIG_CTRL_n registers of the FSI Rx cores.
Please provide a complete register description for these missing RX_TRIG_CTRL_n registers for the 'F2838x device.
