1
0
Static test signal for output when GPOSel=0
1
0
Prevents auto-muxing the GPO with SDO. It always stays GPO.
1
0
Keeps the GPO Driver in output mode (rather than selective drive
based on ChipAddr), unless EnGPO=0.
1
0
Disables the GPO pull-up transistor (suitable for wired or with exter-
nal pull-up or analog lock-detect methods)
1
0
Disables the GPO pull-dn transistor (suitable for wired or with exter-
nal pull-dn or analog lock-detect methods)
