Need Help Connecting ICSP and SPI devices

Does the ICSP and SPI sck, miso, mosi are connected in the mega 2560 board? I need to connect Usb host shield which uses ICSP, micro sd card module which uses spi and RA8875(driver for my 40 pin 5" TFT) which uses spi also. But since my project uses RA8875 driver I need to tri state the miso line, but I am having problem with the connection. Do I need to include the miso of my usb host to the tri state buffer or I can just connect it directly to the board? I have the connection of ra8875 and sdcard module using spi and tri stated miso line connection attached. I have attached also the image of my usb host shield. This is the library I used for my usb host GitHub - felis/USB_Host_Shield_2.0: Revision 2.0 of USB Host Library for Arduino. thank you in advance :slight_smile:
