MMC/SD/SDIO Registers
18.4.27 Force Event Register for Error Interrupt Status (MMCHS_FE)
The Force Event register is not a physically implemented register. Rather, it is an address at which the
Error Interrupt Status register can be written. The effect of a write to this address will be reflected in the
Error Interrupt Status Register, if corresponding bit of the Error Interrupt Status Enable Register is set.
The force event register (MMCHS_FE) is shown in Figure 18-61 and described in Table 18-40.
