does the nrf51822 support 2 SPI masters?

Does the nrf51822 support 2 spi masters (on different pins)? I want 1 spi channel to talk to one set of peripherals, and the other to talk to another set. I see SPI_MASTER1_ENABLE and SPI_MASTER0_ENABLE. I just want to be sure that I can use them simultaneously.

Yes there are two - yes you can use them simultaneously. Note that the two SPIs are shared with the TWIs and the SPI Slave, so if you're using both SPIs then you won't have TWI or SPIS available.
