    Does PSOC4 MCU allows byte access (LDRB instruction)?


      I am trying to access register bits but MCU always go into hardfault handler. From disassembly, I can say whenever it executes ldrb instruction, hard fault happen.

      Although register access works fine as that uses ldr instruction instead of ldrb instruction.


      I am using Cypress-041-41XX PSOC 4100S Pioneer kit.
