-    Most of chip's peripheral signals have direct connection to their dedicated IO_MUX pins. However, the signals can also be routed to any other available pins using the less direct GPIO matrix. If at least one signal is routed through the GPIO matrix, then all signals will be routed through it.
-
-    When an SPI Host is set to 80MHz or lower frequencies, routing SPI pins via GPIO matrix will behave the same comparing to routing them via IOMUX.
