SYS_ERR and CM_STATUS consolidate several sources of interrupts. These sources set the respective bit in the SYS_ERR_INT_FLG and CM_STATUS_INT_FLG registers. Any set bit in the SYS_ERR_INT_FLG and CM_STATUS_INT_FLG registers also sets the GINT (Global Interrupt) bit. GINT has to be cleared before anymore SYS_ERR or CM_STATUS interrupts are generated. If GINT is cleared with the source flags still set, another SYS_ERR or CM_STATUS interrupt is fired; therefore, clear the source flags before clearing GINT.
Figure 3-3 shows the sources for SYS_ERR and CM_STATUS interrupts.
