When TDISEL=0 (J49 short),
ATDI is selected.
When TDISEL=1 (J49 open),
TDI is selected.
ispPAC
J49
CONFIGURATION (1): J49 short and J45 open (default setting)
J39 => for ispPAC programming only
J40 => for XP2 programming only
CONFIGURATION (2): J49 open, with J45 and J52 short
J39 => for programming both XP2 and ispPAC (JTAG chained together)
J40 => not used
For chaining XP2 and
ispPAC together:
(1) Remove the jumper on J49
and install it on J45.
(2) Connect the download
cable to J39.
