Interrupt Line
This register is used to communicate interrupt line routing
information. POST software will write the routing
information into this register as it initiates and configures
the system. The value in this register tells which input of
the system interrupt controller(s) the device’s interrupt pin
has been connected to. Values in this register are
specified by system architecture.
Interrupt Pin
This register tells which interrupt pin the device uses. Its
value is set to 0x01, for the INTA/ signal.
Min_Gnt
This register is used to specify the desired settings for
latency timer values. Min_Gnt is used to specify how long
a burst period the device needs. The value specified in
these registers is in units of 0.25 microseconds. The
LSI53C25A sets this register to 0x11.
