The fourth word contains the status of the firmware. A board operating normally
does not have any flags set except STS_FW_CONFIG_DONE, which means the
board was properly configured before entering operating mode (it is cleared
upon re-entering configuration mode) and STS_FW_OPER_MODE, which means
that the board switched into operating mode without any errors.

Status bits are divided into “conditional” and “sticky”. Conditional bits are set
when a condition arises; they are cleared when the error condition expires.
Sticky bits are persistent once set and are cleared by reading their status.
