Table 2–35
The TDO and nCEO pins are powered by V
TDO is in I/O bank 4 and nCEO is in I/O bank 7. Ideally, the V
for the I/O buffers of any two connected pins are at the same voltage
level. This may not always be possible depending on the V
TDO and nCEO pins on master devices and the configuration voltage level
chosen by V
position in the chain. Master indicates that it is driving out TDO or nCEO
to a slave device. For multi-device passive configuration schemes, the
nCEO pin of the master device drives the nCE pin of the slave device. The
VCCSEL pin on the slave device selects which input buffer is used for nCE.
