Arduino Due - I2C and SPI ports

Official Hardware Mega Due

Hi,

I referred the HW overview diagram and I see Arduino-Due has 2 SPI ports and 2 I2C ports exposed.
Is it my understanding is correct?
Does the Arduino library support above?

There is only SPI0 on a Sam3x8e since there is no PIOE and PIOF (Sam3x datasheet, page 679), but you can have at least two more SPI bus with USART0 and USART1. AFAIK, there is no library for the USART SPI bus, you have to write your own code, and there is a library for the ICSP SPI.

There are two I2C bus (TWI0 ->SDA1/SCL1 and TWI1 ->SDA/SCL) and a library.

Thanks a lot
