TMS320F28379D: Get the counter value with HLC interrupt

Hello,

The HLC instruction set is documented in the device TRM.  On an HLC event you would use a MOV instruction to copy the counter value into a register followed by the PUSH instruction.  INTR # would then send the interrupt to the C28x.

The c28x driverlib documentation can be found in C2000WARE here:

C:/ti/c2000/C2000Ware_<version>/device_support/f2837xd/docs/html/index.html

Here, under the CLB, you will find functions to read, write, and clear the FIFO.  You can also read the counter directly instead of using the HLC to move/push it by using the CLB_getRegister function.

I would suggest these resources for learning more about the CLB:

• Examples for the CLB found in C2000WARE: C:\ti\c2000\C2000Ware_<version>\driverlib\f2837xd\examples\cpu1\clb
• CLB training: https://training.ti.com/c2000-configurable-logic-block-clb-introduction
• On the training webpage there are links to the CLB tool documentation, and application notes related to the CLB.
