XJAPI_SCAN_TYPE

An enumeration of the different scan types available. A value of this type is used as an argument to XJAPI_Scan and XJAPI_ScanMultiple functions to specify the type of JTAG scan to be performed.

The three scan types are:

XJAPI_SCAN_DR

Scan the data register.

XJAPI_SCAN_IR

Scan the instruction register.

XJAPI_SCAN_CLOCK

Just toggle TCK without scanning any data or driving TMS. This is only valid when passed to XJAPI_ScanMultiple; to just clock TCK and perform no other scans use XJAPI_ClockChain.
