Comments
Power-up w/ TEST_SEL = 1 to enter test mode
Cycle power to disable test mode
FSLC./TEST_SEL -->3-level latched input
If power-up w/ V>2.0V then use TEST_SEL
If power-up w/ V<2.0V then use FSLC
FSLB/TEST_MODE -->low Vth input
TEST_MODE is a real time input
If TEST_SEL HW pin is 0 during power-up,
test mode can be invoked through B9b3.
If test mode is invoked by B9b3, only B9b4
is used to select HI-Z or REF/N
FSLB/TEST_Mode pin is not used.
Cycle power to disable test mode, one shot control
B9b3: 1= ENTER TEST MODE, Default = 0 (NORMAL OPERATION)
B9b4: 1= REF/N, Default = 0 (HI-Z)
