Note:

4. Rpu is only needed when the Host Serial Interface is configured for I2C. They are not needed when the Host

Serial Interface is configured for SPI. See I2C Interface section. If Pull-up resistors are used on SCL and SDA,

then both SPI and I2C Modes are possible. If a Pull-up is used on SA0, an alternate slave address is used for

I2C. SPI Mode will be unaltered with the use of Pull-ups for I2C.
