4.18 Interrupt Pin Register
The interrupt pin register tells which interrupt the device uses. This register is hardwired to 01h in the PCI2040 to
indicate that INTA
will be used.

Name Interrupt pin
Type R R R R R R R R
Default 0 0 0 0 0 0 0 1
Register: Interrupt pin
Type: Read-only
Offset: 3Dh
Default: 01h
4.19 MIN_GNT Register
This register specifies the length of the burst period for the device needs in 0.25 µsec units. The default value for this
register is 00h as the PCI2040 is a target-only device.

Default: 00h
4.20 MAX_LAT Register
This register specifies how often the device needs to gain access to the PCI bus in 0.25 µsec units. The default value
for this register is 00h as the PCI2040 is a target-only device.
