RP2350 Datasheet Missing CPICNT and SLEEPCNT registers #427

I am working on a program that needs to know the number of instructions that the M33 cores have executed. ARM provides the equation: number of instructions = CYCCNT - CPICNT - EXCCNT - SLEEPCNT - LSUCNT + FOLDCNT to estimate the number of instructions. However the only documentation for the CPICNT and SLEEPCNT registers seems to be the DWT_SLEEPCNT and DWT_CPICNT to enable CPICNT and SLEEPCNT. However, there is no documentation listing the offset or other information for CPICNT and SLEEPCNT. Can these registers please be added to the documentation?
