Switch Configuration
The switch port assignment is listed in
programming and integrating the Switch Core.
The Switch, controlled with the configuration pin sx_ena, can be programmed to operate
is two modes:
29.3.2 Passthrough Mode
When configuration signal sx_ena is set to '0', the switch logic is bypassed and can be totally
powered down and disabled with, for example, the Switch clocks clk and pclk stopped and
the Switch reset signals reset_clk and reset_pclk set to '1'.
