The following example scans the JTAG instruction register for a 24-bit value:
scan_ir_hw_jtag 24 The following example sends a 24-bit value 0x00_0010 (LSB first) to TDI, captures
the TDO output, applies a mask with 0xF3_FFFF, and compares the returned TDO value
against the specified value -tdo 0x81_8181.
