0x00 = Default Configuration (no configuration is applied)
0x01 = Pull-up
0x02 = Pull-down
0x03 = No Pull
0x04 – 0x7F ; Reserved (do not use)
0x80 – 0xFF ; Vendor-defined values
The output-drive capability, in hundredths of milliamperes, to
be applied when configuring the pin for output (high byte).
_DRS[7:0]
The output-drive capability, in hundredths of milliamperes, to
be applied when configuring the pin for output (high byte).
_DRS[15:8]
The debounce timeout, in hundredths of milliseconds, to be
applied when configuring the pin for interrupt (low byte).
_DBT[7:0]
The debounce timeout, in hundredths of milliseconds, to be
applied when configuring the pin for interrupt (high byte).
_DBT [15:8]
Offset to the start of the pin table (low byte). The offset is
relative to the start of this descriptor.
NOTE: The number of pins in the table can be calculated from
PinCount = (Resource Source Name Offset – Pin Table
Offset) / 2
Offset to the start of the pin table (high byte). The offset is
relative to the start of this descriptor.
Reserved for future use. This field must be 0.
Offset to the start of the resource source name (low byte). The
offset is relative to the start of this descriptor.
NOTE: The length of the ResourceSource name string can be
calculated from Length L = Vendor Data Offset – Resource
Source Name Offset. The length includes the string’s
terminating NULL character (if present)
Offset to the start of the resource source name (high byte).
The offset is relative to the start of this descriptor.
(low byte) Offset to the start of the Vendor-defined Data (the
last byte of the ResourceSource + 1). This value must always
be valid to allow for length calculations. In the case where
there is no Vendor Data, this offset still must refer to the last
byte of the ResourceSource + 1.
The offset is relative to the start of this descriptor.
