I am totally new to MCU's :mansurprised: .....i need help with connecting nRF24l01 transiver to demo9s08ll16 board's i/0 pins..... i looked at datasheet but still cant get it, its confusing for example when connecting MOSI of transiver to the board there are two pins, one at 42 and another at 28 they both have the MOSI name; now which one has to be selected.... How pins are connected generaly (not for this MCU for others)? Thx

 

nRF24ll01 pins information:

demo9s08ll16 data sheet page 5 has the pin connection information:

Regarding SPI on LL16. What pins SPI is routed to is controlled by SPIPS bit (SOPT2 register). Either you may choose to have SPI routed to pins PTA0-PTA3 or to PTB4-PTB7.
