4.6.4 LPT JTAG Setting

The LPT based JTAG controller does not have a fixed schematic, even for WIGGLER and SDT-JTAG. Some
JTAG emulator comes with nSRST, while others don’t have. Some JTAG emulator provides separate nSRST and
nTRST, while others connected them together. To support different LPT based JTAG emulators, H-JTAG provides
a flexible configuration interface. What user needs to do is tell H-Jtag exactly how the JTAG emulator is
connected to LPT.

The LPT provides 8 data bits, D0-D7, as output and several status bits as input. The data bits can be used as
JTAG output signals, TMS, TCK, TDI, nSRST and nTRST. Any one of the status bits can be used as input to
sample TDO. The JTAG configuration is to specify how the JTAG signals are connected with the data bits and
status bits. On some JTAG emulator, the nSRST and nTRST are inverted. These also need to be specified in the
JTAG configuration.

Next, let’s look at an illustrative example. The schematic of the JTAG emulator used in the example is show
in Fig 4-7. The connection between LPT and JTAG can be obtained from the schematic and is listed in following
table. Please note that the nTRST signal is inverted and no nSRST signal is provided.
--------------------------------------
TMS ------>> LPT D1 (PIN3)
TCK ------>> LPT D2 (PIN4)
TDI ------>> LPT D3 (PIN5)
TDO ------>> LPT BUSY (PIN11)
nTRST ---->> LPT D0 (PIN2) INVERTED
nSRST <<---- X NOT AVAILABLE
