Updated by SSM_RESET or SPI write while in DIAG state
0000 = all outputs inactive
0001 = ARM 1 pin active
0010 = ARM 2 pin active
0011 = ARM 3 pin active
0100 = ARM 4 pin active
0101 = PSINHB pin inactive (high)
0110 = VSF regulator active
0111 = HS squib/pyroswitch driver FET active
1000 = LS squib/pyroswitch driver FET active
1001 = Output deployment timing pulses on ARM1 (separated by 8 ms)
1010 = HS squib/pyroswitch driver FET active to test full path (FET
switched off by the
comparator used in the deployment current timer monitor)
1011 - 1111 = all outputs inactive
