When card slot is empty or the power supply is off, each card slot has independently power management
because each slot has its own buffers and transceivers. In order to achieve the low power consumption especially for
the notebook PCs, each address mapping circuit will be powered down when it is not activated. In addition to the
function, setting the power down bit in the global control register to “1” enables the RF5C296/RF5C396 to go into
the power down mode. There is a single power down control bit which can be written with either a Slot#0 or Slot#1
Global Control Register Index. Setting this bit to “1” goes into the power down mode. Even in the power down
mode, RF5C296/RF5C396 can generate a card status change interrupt and PC Card interrupt for I/O cards. The
RF5C296/RF5C396 can also generate the RI_OUT# signal when configured for ring indicate resume from I/O
cards. In this Power down mode, the following ISA bus signals will be ignored.
SD[15 : 0], LA[23 : 17], SA[16 : 0], IORD#, IOWR#, AEN, BALE, SYSCLK, MEMW#, MEMR#, SBHE#
There are three/four different power nets ; VCC for ISA bus interface, VCC for core logic, VCC for card slot
interface ; to be handled in RF5C296/RF5C396. Each of these power nets can be independently running at 3.3V or
5V. All of the voltage combinations listed on the next page are supported. RF5C296/RF5C396 can operate even with
the single power supply of 5V or 3.3V
