The pullup resistors for the input signals are built in and can be disabled if external pullups are necessary (the external pullups
can be on a different power plane).
In Suspend mode, the signals can be configured for: a card not plugged in (inputs terminated with internal resistors), a card
plugged in and powered (the output signals drive out inactive), a card plugged in and powered and at 5 V (the inactive High
output signals are three-stated and pullup resistors should be put on the board), and a card plugged in and powered off (the
signals terminated with pulldown resistors) (Power-Down Group G).
Summary: The outputs are built-in pulldown resistors that are invoked by:
Summary: The inputs are built-in pullup and pulldown resistors that are invoked by:
and ICDIR are not supported on the ÉlanSC410 microcontroller.
–Suspend and PC Card Socket A is programmed to be powered off in Suspend (Power-Down Group G).
–These are not pulldowns for normal operation. These are driven outputs.
–Reset invokes pullups.
–During normal operation, the pullup resistors can be disabled by a register bit.
–During Suspend mode, the inputs will have pulldowns if the PC Card Socket A interface is programmed to be powered off
in Suspend mode (Power-Down Group G). If the socket is not programmed to be powered off in Suspend mode, the inputs
have the same state as when operating: the pullups are programmable to be enabled or not.
