F
Path: Keyword
Type: Executable
Syntax: F [0] | [n]
Range: Hexmask - 0..FF
Notes: The F request displays a hex bitmap for each fault table specified in the mask. The
mask is supplied in hex. Use a mask of 0 to display all fault bitmaps. This is a
detailed fault report that returns 8 ASCII encoded hex digits. Each digit represents
four bits in the fault table. The fault table is the same as the faults listed by the
LIST-FAULTS command.
BIT FAULT BIT FAULT
1 LOW-INPUT-SIGNAL 12 BDC1-FAULT
2 INPUT-SIGNAL-SATURATED 13 BDC2-FAULT
3 MCU-LINKLOSS 14 BDC3-FAULT
4 DSP-LINKLOSS 15 BDC4-FAULT
5 DSP-DATALOSS 16 PLL1-UNLOCKED
6 SPU-RESPONSE-OVERFLOW 17 PLL2-UNLOCKED
7 TBT-LINKLOSS 18 FACTORY-BURN-IN
8 TBT-FAULT 19 NVRAM-CORRUPTED
9 TBT-IN-LOCAL 20 FAULTY-MUTE-SWITCH
10 OUT-OF-BAND 21 SPU-LINK-LOCKED
11 INVALID-BAND-SETUP
The string reads right to left. Bit 1 is on the far right. For example
> F 0
0000101D
>
Expanding the string 0000101D showing each bit
0000 0000 0000 0000 0001 0000 0001 1101
Reading right to left, bits 1,3 4,5, and 13 are set, which correspond to the
following faults:
1 LOW-INPUT-SIGNAL
3 MCU-LINKLOSS
4 DSP-LINKLOSS
5 DSP-DATALOSS
13 BDC2-FAULT
