Description
Multi-Function General Purpose Counter #2 - Compare 1 Out.
An output from the counter that, when asserted, indicates the
counter has reached the conditions set up in the counter’s
Compare 1 registers.
Multi-Function General Purpose Counter #2 - Compare 2 Out.
Output from the counter that, when asserted, indicates the counter
has reached the conditions set up in the counter’s Compare 2
registers.
Multi-Function General Purpose Counter #2 - Restart. An input
to the counter that causes it to be reset to initial conditions and
then to resume counting.
Multi-Function General Purpose Counter #7 - Compare 1 Out.
An output from the counter that, when asserted, indicates the
counter has reached the conditions set up in the counter’s
Compare 1 registers.
Multi-Function General Purpose Counter #7 - Compare 2 Out.
An output from the counter that, when asserted, indicates the
counter has reached the conditions set up in the counter’s
Compare 2 registers.
Multi-Function General Purpose Counter #7 - Restart. An input
to the counter that causes it to be reset to initial conditions and
then to resume counting.
PCI Interrupt A. This is a “recommended use” for GPIO0,
because this GPIO has a PCI-compatible output type.
PCI Interrupt B. This is a “recommended use” for GPIO7,
because this GPIO has a PCI-compatible output type.
Power Management Event. This is a “recommended use” for
GPIO26. By mapping this GPIO (or any other) to the PME# func-
tion, the CS5535 may be awakened from a Sleep state when the
mapped ball (in the recommended case, ball B7) is pulled low.
