CL-PD6833
PCI-to-CardBus Host Adapter
Bits 6:4 — V
Bit 7 — Stop Clock
Bits 31:8 — Reserved
June 1998
These bits are used to control the power to the PC Card using external control logic. The
CL-PD6833 determines the voltages that can be applied by decoding the CD and VS signals
according to the CardBus specification , which are reflected in the Present State register. The
settings in the Present State register that determine the voltages available in the system
determine the V
apply the correct value of V
applied to a socket. The voltages available are shown in the Status register.
This bit is not implemented in the CL-PD6833.
