!***********************   Backtrace Information   *****************

trace Serial_data to Serial_clock,Address,Test

!This test anticipates all possible topologies.  The units that
!are not necessary can be commented out.
!The pin 'Test' (pin 7) has not been tested since it requires a voltage
!of 1V to 2V to force the device into the power saving mode.  For normal
!operation, 'Test' is set to 0V.
!Note that when 'Test' is 1V to 2V, the device enters the power
!saving mode and 'Test',Serial_data,and Serial_clock take on the
!voltage VDDR which is the voltage maintained by 'Test' until
!'Test' is brought back to 0V.
!Note that pull-ups are required on pins 5 and 6 for this test to operate
!properly.


warning "Pull-ups required on Serial_data and Serial_clock (pins 5,6)"
warning "for entire test to run."
