POWER_DESCR

The POWER_DESCR 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.

Syntax

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

Members

ValidMask

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 a one, then the NominalV member contains a valid voltage. If the following bit is a one, then the MinV member is valid, and so on. (Output)

NominalV

Nominal operating supply voltage. (Output)

MinV

Minimum operating supply voltage. (Output)

MaxV

Maximum operating supply voltage. (Output)

StaticI

Continuous supply current required. (Output)

AvgI

Maximum current required averaged over 1 second. (Output)

PeakI

Maximum current required averaged over 10 milliseconds. (Output)

PowerDownI

Power-down supply current required. (Output)

Remarks

Voltages are expressed in one-tenth volt increments, so a value of 50 represents 5 volts. The currents are expressed in milliamps.
