Ideally, the V
at the same voltage level. This may not always be possible depending on
the V
configuration voltage level chosen by VCCSEL on slave devices. Master
and slave devices can be in any 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. When VCCSEL
is logic high, it selects the 1.8-V/1.5-V buffer powered by V
VCCSEL is logic low it selects the 3.3-V/2.5-V input buffer powered by
