Do I understand correctly that the same hardware module is used for SPI, TWI, and UART?
Does such a system apply to all NRF products?

The reason for this is that the peripherals SPIM, SPIS, TWIM, TWIS, and UARTE in the nRF9160 shares address space. This means that if instance x (where 0<=x<=3) is used by one of the peripherals, none of the other peripherals can use the same instance.

Check out the register addresses for these peripherals in the infocenter:
