COMPUTER ACCESS TECHNOLOGY CORPORATION USB REQUEST DEFINITION (.REQ) FILES

Reference Manual

if the bmRequestType value is 0x01, the WordValue definition is used to

decode the request; on the other hand, if the value is 0x02, then the

FormatValue definition is used.

Default Branches

A default branch can be added to the Depends(...) definition:

wIndex=

{

Depends(bmRequestType)=

{

0x01=

{

FormatValue=Interface # %i status requested

}

FormatValue=Undefined bmRequestType, wIndex is

0x%02X

}

If the value of bmRequestType is 0x01, then the first FormatValue defini-

tion is applied. Otherwise, it defaults to the second FormatValue definition. The

default definition must be last in the list.

Mask Values

Use a bitwise & (AND) mask construct within Depends(...) to mask a value:

wValue=

{

Depends(wValue&0xFF00)=

{

0x0100=

{

WordValue=

{

0x01=One

}

0x0200=

{

FormatValue=Two %d

}

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 ... 35 36
