CL-PD6833
PCI-to-CardBus Host Adapter
Bits 6:4 — VCC Control
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 VCC options. The value written to this register must agree with the value needed to
apply the correct value of VCC. The CL-PD6833 must not allow an incorrect VCC voltage to be
applied to a socket. The voltages available are shown in the Status register.
