Self-Test
Function
TCA Interrupt
Generates an interrupt.
Tests to see if the Interrupt Service Routine (ISR) can be
reached and then turns off interrupts and makes sure that the
ISR is not reached.
TCA FIFO
Loads up the TCA FIFO at longwords with an increasing
value, starting at 1 and ending with 512. The FIFO is then
emptied and the count is checked against the read values from
the FIFO.
An error is reported if:
FIFO EMPTY does not get reset to 0 (empty) after
reading 512.
The data read does not correspond to its count.
TCA Trigger
Tests DMA functionality through the Read Trigger test and
through the Write Trigger test.
TCA Size Bus
Accesses TURBOchannel Slot 0 space to see if a device is
there.
If a TURBOchannel device is present, no TURBOchannel
Timeout occurs.
When the SHOW CONFIG is entered at the console prompt,
the status of this test is stated as either:
OPT PRES V1.0
NOOPT PRES V1.0
