C5. VPD Test
Function: It saves the content of VPD before it performs the test. Once
the test is done, this function writes one of the following five pattern test
data into VPD memory:
 0xFF
 0xAA
 0x55
 increment data
 decrement data
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
