TI Hercules ARM Cortex-R4/R5 full tech ref manual / user guide

v01d
Expert 2035 points

I see this presentation from TI:

https://training.ti.com/sites/default/files/docs/hercules_cortexr4_system_architecture_cp15.pdf

Some slides refer to the ARM's Cortex R4 tech ref manual (slide 3 is snapshot from it).

But is there TI's own specific Hecules Cortex R4 implementation manual  / full reference guide?   to supplement ARM's, and perhaps cover MCU's implementer's defined parts..?

    The TMS570LSx/LCx series TRM contains references to the R4F/R5F TRM from ARM. The CPU core, MPU, FPU, PMU etc that are parts of ARM IP are not covered in TI data manual and TRM.

    Ok, so there isn't any extension or as ARM arch ref manual would call implementation defined (here === TI's SoC) behavior ? 

    (just for example, ignore for question : a hint instruction wfi may trigger some special lower power mode, but that depends on the chip implementation )
