EALE
LBI Interrupt Input Control
This bit selects whether the LBI interrupt input pin LINTI is a low or high
active input signal:
LINTIC=’0’
LINTIC=’1’
LBI External Bus Controller Reset
Via this bit the complete LBI block can be reset (disabled) or enabled:
EBCRES
=’0’
EBCRES
=’1’
Note: This Reset control bit is not self clearing. The LBI block remains in
LBI Extended ALE
This bit selects whether the LBI ALE output signal is generated for one
LBI clock period or an extended period:
EALE=’0’
EALE=’1’
its reset state, until a ’1’ is written to bit ’EBCRES’.
LINTI input pin ia a low active input signal, i.e. LINTI=’0’
generates an interrupt indication.
LINTI input pin ia a high active input signal, i.e. LINTI=’1’
generates an interrupt indication.
The LBIl block is forced into its reset state. Also all
dedicated pins are in reset state (same as hardware
reset).
The LBI block isenabled. The function depends to the
selected configuration.
ALE signal high time is 1 LBI clock period.
ALE signal high time is 1 LBI clock period + 1 PCI clock
high time.
