Test 1 External Interrupts

This test verifies the external interrupt cables. The test is used to verify either a
single external interrupt cable or all external interrupt cables. You select the level of
testing during program initialization. Refer to Chapter 2 for a description of the
initialization options.
Test 1 uses the external interrupt acknowledge signal line (XIACK0 through
XIACK7) as the source of the external interrupt under test. The output from this
signal is connected to the corresponding input signal line (XIRQ0 through XIRQ7).
For example, XIACK7 is connected to XIRQ7. The test generates the XIACK output
signal by writing to the corresponding ISTS register in the TS80. Refer to Chapter 1
for cabling information.
