The SEM status register contains the status signals from the TMR SEM core. This is a read only register. If a write request is issued to the SEM status register it does nothing but generate a write acknowledgment. The register bit assignment is shown in Table: SEM Status Register (SEMSR) and described in Table: SEM Status Register Bit Definitions . The register is only implemented if C_SEM_INTERFACE is set to 1.
