SWRZ073C May 2017 – May 2021 IWR1642
Read-data from internal registers of PCR is not reliable. Shared PCS region protection is also not supported
IWR1642 ES1.0 and ES2.0
The main subsystem has PCR interconnect that manages the accesses to the peripheral registers and peripheral memories, and provides a global reset for all peripherals. The read-data from PCR is getting corrupted before handing it of to VBUSP interconnect. So any partial write to PCR-registers is not reliable. Peripheral access is blocked by writing to internal registers which is not feasible.
Shared PCS region protection is also not supported
No workaround
