Description
Writing 1 to and of these bits configures the corresponding
GPIO[3:0] pin as an input only. The output driver is tristated.
Writing 0 to this register has no effect and will reflect the last value
written when read.
Reset to 0.
Writing 1 to and of these bits configures the corresponding
GPIO[3:0] pin as bidirectional. The output driver is enabled and
drives the value set in the output data register (65h). Writing 0 to this
register has no effect and will reflect the last value written when read.
Reset to 0.
Reserved. Returns 0 when read. Reset to 0.
Reads the state of the GPIO[3:0] pins. The state is updated on the PCI
clock following a change in the GPIO[3:0] pins.
Description
If either bit is 0, then S_CLKOUT [0] is enabled.
If both bits are 1, then S_CLKOUT [0] is disabled.
If either bit is 0, then S_CLKOUT [1] is enabled.
If both bits are 1, then S_CLKOUT [1] is disabled.
If either bit is 0, then S_CLKOUT [2] is enabled.
If both bits are 1, then S_CLKOUT [2] is disabled.
If either bit is 0, then S_CLKOUT [3] is enabled.
If both bits are 1, then S_CLKOUT [3] is disabled.
If bit is 0, then S_CLKOUT [4] is enabled.
If bit is 1, then S_CLKOUT [4] is disabled and driven low.
If bit is 0, then S_CLKOUT [5] is enabled.
If bit is 1, then S_CLKOUT [5] is disabled and driven low.
If bit is 0, then S_CLKOUT [6] is enabled.
If bit is 1, then S_CLKOUT [6] is disabled and driven low.
If bit is 0, then S_CLKOUT [7] is enabled.
If bit is 1, then S_CLKOUT [7] is disabled and driven low.
If bit is 0, then S_CLKOUT [8] is enabled.
If bit is 1, then S_CLKOUT [8] is disabled and driven low.
If bit is 0, then S_CLKOUT [9] is enabled.
If bit is 1, then S_CLKOUT [9] is disabled and driven low.
Reserved. Returns 00 when read.
Description
1: Signal P_SERR_L was asserted because an address parity error
was detected on P or S bus.
Reset to 0
1: Signal P_SERR_L was asserted because a posted write data parity
error was detected on the target bus.
Reset to 0
1: Signal P_SERR_L was asserted because the bridge was unable to
deliver post memory write data to the target after 2
