HMATRIX
DSP Operations
1. In the HMATRIX PRAS and PRBS registers MxPR fields are only two bits
1. Instruction breakpoints affected on all MAC instruction
In the HMATRIX PRAS and PRBS registers MxPR fields are only two bits wide, instead of
four bits. The unused bits are undefined when reading the registers.
Fix/Workaround
Mask undefined bits when reading PRAS and PRBS.
Hardware breakpoints on MAC instructions may corrupt the destination register of the MAC
instruction.
Fix/Workaround
Place breakpoints on earlier or later instructions.
