SCANSTA112 hardware design queries

Hi

I have following queries regarding Scansta112

1) When a particular LSP is deselected by pulling its LSPsel LOW, is the LSP TRISTATED ? Or does it drive HIGH or LOW?

2) How many devices at max can be connected to a particular LSP without having to add additional buffer for TMS or TCK?

For eg, in one of our designs we intend to connect 4 ASICs with 8pF input capacitance.
