BIST Capable (Fixed Value: 0)
Indicates that the BIST function is not being supported.
Multi-Function (Fixed Value: 0)
0: Indicates that the device is a single-function device.
Header Type (Default: 0x00)
Indicates the Header type.
0000000: Header Type 0
It is possible to change the header type by loading data from Configuration
EEPROM during initialization.
Latency Timer (Default: 0x00)
Sets the latency timer value. Specifies the PCI Bus clock count during
which to abort access when the GNT* signal is deasserted during PCI
access. Since the lower two bits are fixed to “0”, cycle counts can only be
specified in multiples of 4.
Cache Line Size (Default: 0x00)
Is used to select the PCI Bus command during a Burst Read transaction.
See “10.3.3 Supported PCI Bus Commands)” for more information.
