POWER_DESCR

  • Article

This structure contains the characteristics of one of the PC Card voltage sources: Vcc, Vpp1, or Vpp2. The PARSED_CFTABLE structure uses the POWER_DESCR structure to define its VccDescr, Vpp1Descr, and Vpp2Descr members.

typedef struct { 
UINT8 ValidMask; 
UINT8 NominalV; 
UINT8 MinV; 
UINT8 MaxV; 
UINT8 StaticI; 
UINT8 AvgI; 
UINT8 PeakI; 
UINT8 PowerDownI; 
} POWER_DESCR;

Members

  • ValidMask
    [OUT] Specifies a bitmask identifying the members in the POWER_DESCR structure containing valid values. A CISTPL_CFTABLE_ENTRY tuple might not include all seven power characteristics. If the first bit of ValidMask is 1, the NominalV member contains a valid voltage. If the following bit is 1, the MinV member 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.
