Feedback on Control architecture

Good document Ravi, My understanding and queries are below (correct any
wrong inference please)

**TxController and RXcontroller are hardware modules that controls the
data-path components and its corresponding multiplexers in the TX and RX
respectively.
Each module would be designed as a sequencer or data-flow manager among
the data-path elements.
For instance: in TX, The TXcontroller will decide when to initialize
and/or enable the CRC16 component to start processing on the pay-load
(plain user-data) coming from the TX buffer; then it informs that CRC16
at the end of the user-data by asserting the "Drain" signal HIGH , and
also maintain it for 16 cycles which are needed to append the CRC16
value from the LFSR to the pay-load.
and so on for each module according to each processing scheme.

**The micro-controller will have a firm-ware (c-code) which should be
simple (due to moving much of the control actions to the HW
controllers),and the Ucontroller should be like a manager of the HW
controllers actions. (I need an example for this scenario from your
side) to point out for instance how the Ucontroller manage the actions
of forinstance the TXcontroller along the processing among the data-path
components.

** Timerblock module: I need to know the function of it. Is it only
sending interrupts to the Ucontroller.? and what are these interrupts. ?
this is vague for me.

**Headerbuffer:
This buffer stores the header of the data to be transmitted as I
understand. (the header on which the CRC8 HEC has to be evaluated)isn't
it ?
I need to know why it is interacting with Ucontroller.?
** CS register
IS it the current status register. In other words a register that holds
the BT system states .. If yes , please list what states that we would
be working with. 
It is reasonable that CS_Reg informs the Ucontroller of the Current
state and then the Ucontroller has a scenario to be executed represeted
in control actions for the data-path controllers and etc.. 

Radio-Interface block: 

what does it inform the Ucontroller with and what is it getting in
return from its side. And is this dependant on the RF that we will
use.(we need to be independent somehow to work with all RFs available).

An explanation of the involved interactions of the control architecture
would be very helpful for all of us...
 
I am looking forward to having your feedback and comments.

Ps: We are all learning here and this is the main objective; Hence Could
u please all contribute with your understanding, feedback,
queries...etc..The most of joy happens when many of us working as one
hand to reach the same goal.......Think of it seriously all here and Let
Us realize NOUR chip.we are ahead of starting off a real development
phase of a very state-of-the-art project ...Waiting for YOU ALL>
