FS_C/TEST_SEL is a 3-level latched input.
o Power-up w/ V >= 2.0V to select TEST
o Power-up w/ V < 2.0V to have pin function as
FS_C.
When pin is FS_C, VIH_FS and VIL_FS levels
apply.
FS_B/TEST_MODE is a low-threshold input
o VIH_FS and VIL_FS levels apply.
o TEST_MODE is a real time input
TEST_SEL can be invoked after power up
through SMBus B6b6.
o If TEST is selected by B6b6, only B6b7 controls
TEST_MODE. The FS_B/TEST_Mode pin is not
used.
Power must be cycled to exit TEST.
