Other Parts Discussed in Thread: TMS320F28379D

In TMS320F28379D we found CLB block.
In Position Manager symbol library we can read that TMS320F28379D has 4 CLB blocks, they have own XBAR, configured LUT3, as well as registers or triggers.

00000000 T _Clb_configClbXbar

0000067b T _endat22_CLB1_config
00000459 T _endat22_CLB2_config
0000022a T _endat22_CLB3_config
00000000 T _endat22_CLB4_config

000000a6 T _Clb_clearFIFOs
00000069 T _Clb_clearHLC
00000057 T _Clb_configLut3
00000015 T _Clb_getCRC
00000000 T _Clb_writeInterface

Configuration registers described in CMD file for this controller:

   CLB1_LOGICCFG      : origin = 0x003000, length = 0x000040
   CLB1_LOGICCTL      : origin = 0x003100, length = 0x000040
   CLB1_DATAXCHG      : origin = 0x003200, length = 0x000200
   CLB2_LOGICCFG      : origin = 0x003400, length = 0x000040
   CLB2_LOGICCTL      : origin = 0x003500, length = 0x000040
   CLB2_DATAXCHG      : origin = 0x003600, length = 0x000200
   CLB3_LOGICCFG      : origin = 0x003800, length = 0x000040
   CLB3_LOGICCTL      : origin = 0x003900, length = 0x000040
   CLB3_DATAXCHG      : origin = 0x003A00, length = 0x000200
   CLB4_LOGICCFG      : origin = 0x003C00, length = 0x000040
   CLB4_LOGICCTL      : origin = 0x003D00, length = 0x000040
   CLB4_DATAXCHG      : origin = 0x003E00, length = 0x000200

Can we get detail description of this block?

    Vladamir,

    As the datasheet says,

    "TI uses the CLB to offer additional interfacing and control features for select C2000 devices. Functions that would otherwise be accomplished using external logic devices are now provided by on-chip TI solutions."

    These are TI solutions and we do not make the inner-workings of CLB available to customers.  If you have a use case for the CLB that you are interested in TI providing, feel free to contact me directly with that idea and we can add it to our list of future CLB projects if it is not already comprehended.

    Thanks for your interest in C2000(tm) MCUs!
