Elprotronic MSP430 - 4.6 Customized JTAG Instruction

4.6 Customized JTAG instruction
Customized JTAG instruction allows to create any sequence on the JTAG output lines - TMS,
TDO, TCK and read sequence on the input TDI line. These instructions are useful in development -
not exactly related to MSP430 microcontrollers. Instructions allows to transfer sequences from PC
via USB to target device. JTAG protocol and list of high level instructions should be created by user.
F_init_custom_jtag
F_init_custom_jtag - Switch FPA from MSP430 protocol to custom ized JTAG
stream..
VALID FPA index - ( 1 to 64 ) or 0 (ALL FPAs) executed sequentially.
NOTE: Instruction not supported in BSL and Fast BSL.
Syntax:
MSPPRG_API void F_init_custom_jtag( INT_X state, INT_X Vcc_index );
state - 0 - turn-OFF FPA
state - 1 - turn-ON FPA and create default (all zeros) states of I/O lines.
Vcc_index - Vcc from FPA
0 - 2.2 V
1 - 2.4 V
2 - 2.6 V
3 - 2.8 V
4 - 3.0 V
5 - 3.2 V
6 - 3.4 V
7 - 3.6 V
F_custom_jtag_stream
F_custom_jtag_stream - Transfer JTAG stream taken from the data buffer.
VALID FPA index - ( 1 to 64 ) or 0 (ALL FPAs) executed sequentially.
NOTE: Instruction not supported in BSL and Fast BSL.
Syntax:
MSPPRG_API INT_X F_custom_jtag_stream( INT_X mode, INT_X size,
BYTE * data_out, BYTE * data_in );
