Continued
EPROM test
Checks the EPROM dual access; EPROM bus arbitration.
Host Interrupt test
Checks the host interrupt; verifies option can interrupt the
CPU.
Host Loopback test
Checks the host buffer loopback and interrupt; moves data
from the CPU to the communication option, loops it back and
waits for an interrupt.
Reset test
Resets the communication options and waits for an interrupt.

Adapter
Self-Test (T 13)
Table 5–7 describes the tests executed during power-up TCA self-
test. The power-up self-test is automatically invoked during
the initial power-up of the VS4000 hardware and tests the
TURBOchannel adapter in a sequential manner.

Self-Test
Function
TCA Register
Tests the following functions of the CSR:
RESET (toggle and check bit in CSR)
TURBOchannel Timeout (read the TURBOchannel while
holding RESET)
FIFO empty bit set and cleared by writing and reading
FIFO
INV by doing an invalid map DMA
