18.5.1.25 SD_FE Register (offset = 250h) [reset = 0h]
SD_FE is shown in Figure 18-61 and described in Table 18-44.
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.
