NOTE:
G_PAR
Signal Name
PCIRST# from the ICH3-M is connected to RSTIN# and is used to reset AGP interface logic within the
MCH-M. The AGP agent will also use PCIRST# provided by the ICH3-M as an input to reset its internal
logic.
Type
AGP
I/O
Parity
During FRAME# Operation: G_PAR is driven by the MCH-M when it acts as a
FRAME#-based AGP initiator during address and data phases for a write cycle,
and during the address phase for a read cycle. G_PAR is driven by the MCH-M
when it acts as a FRAME#-based AGP target during each data phase of a
FRAME#-based AGP memory read cycle. Even parity is generated across
G_AD[31:0] and G_CBE[3:0]#.
During SBA and PIPE# Operation: This signal is not used during SBA and PIPE#
operation.
