5.10.2.12JTAG_Store()
Description
Stores a JTAG seuqnece (max. 64 bits per pin) in the DLL JTAG buffer.
Prototype
__api__ int JTAG_Store(unsigned __int64 tms, unsigned __int64 tdi, int
NumBits);
5.10.2.13JTAG_GetU32()
Description
Gets 32 bits JTAG data, starting at given bit position.
Prototype
__api__ int JTAG_GetU32(int BitPos);
5.10.2.14JTAG_WriteClocks()
Description
Writes a given number of clocks.
Prototype
__api__ int JTAG_WriteClocks(int NumClocks);
5.10.2.15JTAG_StoreClocks()
Description
Stores a given number of clocks in the DLL JTAG buffer.
Prototype
__api__ int JTAG_StoreClocks(int NumClocks);
5.10.2.16JTAG_Reset()
Description
Performs a TAP reset and tries to auto-detect the JTAG chain (Total IRLen, Number of
devices). If auto-detection was successful, the global DLL variables which determine
the JTAG chain configuration, are set to the correct values. For more information
about the known global DLL variables, please refer to Global DLL variables on
page 167.
Note: This will not work for devices which need some special init (for example to
add the core to the JTAG chain), which is lost at a TAP reset.
Prototype
__api__ int JTAG_Reset(void);
5.10.2.17SYS_Sleep()
Description
Waits for a given number of miliseconds. During this time, J-Link does not communi-
cate with the target.
Prototype
__api__ int SYS_Sleep(int Delayms);
