C5. VPD Test
Function: It saves the content of VPD first before perform the test. Once it
is done, it writes one of the five pattern test data, 0xFF, 0xAA, 0x55,
increment data, or decrement data, into VPD memory. By default,
increment data pattern is used. It writes and reads back the data for the
entire test range, and then restores the original content.
Default: Disabled
C6. ASF Test
Function: m
1. Reset test.
Setting reset bit, poll for self-clearing. Verify reset value of registers.
2. Event Mapping Test
Setting SMB_ATTN bit. By changing ASF_ATTN LOC bits, verify the
mapping bits in TX_CPU or RX_CPU event bits.
3. Counter Test
Clear WG_TO, HB_TO, PA_TO, PL_TO, RT_TO bits by setting those
bits. Make sure the bits clear.
Clear Timestamp Counter. Writing a value 1 into each PL, PA, HB, WG,
RT counters. Set TSC_EN bit.
Poll each PA_TO bit and count up to 50 times. Check if PL_TO gets set
at the end of 50 times. Continue to count up to 200 times. Check if all
other TO bits are set and verify Timestamp Counter is incremented.
C7. ROM Expansion Test
Function: This function tests the ability to enable/disable/access the
expansion ROM on the device.
D1. Mac Loopback Test
Function: This is internal loopback data transmit/receive test. It initializes
the MAC into internal loopback mode and transmits 100 packets. The data
should be routed back to the receive channel and received by the receive
routine which verifies the integrity of data. One Gigabit rate is used for this
test.
Default: Enabled
