    EVK-R41Z - User guide 2.4.3 User LEDs The R41Z evaluation board features an RGB LED and a separate blue LED. Since the GPIO used are shared with the expansion header, solder jumpers are provided to disconnect the LEDs if required. Since the LEDs are powered from the peripheral power bus VIO, they will be powered directly by the R41Z module when it is operating in either Buck or Boost DC-DC mode.

AT45DB041E-MHN2B-T). The flash uses an SPI interface with signals shared with the expansion headers. When using multiple Chip Select (CS) signals, this allows the same SPI bus to be used with both the Flash module and one or more SPI devices on an expansion shield.
