This structure contains the characteristics of one of the PC Card voltage sources: Vcc, Vpp1, or Vpp2. The PARSED_CFTABLEstructure uses the POWER_DESCRstructure to define its VccDescr, Vpp1Descr, and Vpp2Descrmembers.

Members
- ValidMask
- [OUT] Specifies a bitmask identifying the members in the POWER_DESCRstructure containing valid values. A CISTPL_CFTABLE_ENTRY tuple might not include all seven power characteristics. If the first bit of ValidMaskis 1, the NominalVmember contains a valid voltage. If the following bit is 1, the MinVmember is valid, and so on.
- NominalV
- [OUT] Specifies the nominal operating supply voltage.
- MinV
- [OUT] Specifies the minimum operating supply voltage.
- MaxV
- [OUT] Specifies the maximum operating supply voltage.
- StaticI
- [OUT] Specifies that continuous supply current is required
- AvgI
- [OUT] Specifies that maximum current averaged over 1 second is required.
- PeakI
- [OUT] Specifies that maximum current averaged over 10 milliseconds is required.
- PowerDownI
- [OUT] Specifies that power-down supply current is required.
Remarks
Voltages are expressed in one-tenth volt increments, so a value of 50 represents 5 volts. The currents are expressed in milliamps.
