-JTAG protocol decoder.
-
JTAG (Joint Test Action Group), a.k.a. "IEEE 1149.1: Standard Test Access Port
and Boundary-Scan Architecture", is a protocol used for testing, debugging,
and flashing various digital ICs.
-TODO: Protocol details.
-
-Protocol output format (WORK IN PROGRESS!):
-
-JTAG packet:
-[<packet-type>, <data>]
-
-<packet-type> is one of:
- - 'NEW STATE': <data> is the new state of the JTAG state machine.
- Valid values: 'TEST-LOGIC-RESET', 'RUN-TEST/IDLE', 'SELECT-DR-SCAN',
- 'CAPTURE-DR', 'SHIFT-DR', 'EXIT1-DR', 'PAUSE-DR', 'EXIT2-DR', 'UPDATE-DR',
- 'SELECT-IR-SCAN', 'CAPTURE-IR', 'SHIFT-IR', 'EXIT1-IR', 'PAUSE-IR',
- 'EXIT2-IR', 'UPDATE-IR'.
- - 'IR TDI': Bitstring that was clocked into the IR register.
- - 'IR TDO': Bitstring that was clocked out of the IR register.
- - 'DR TDI': Bitstring that was clocked into the DR register.
- - 'DR TDO': Bitstring that was clocked out of the DR register.
- - ...
-
-All bitstrings are a sequence of '1' and '0' characters. The right-most
-character in the bitstring is the LSB. Example: '01110001' (1 is LSB).
