Note

The motherboard

Time-of-Year

(TOY) clock updates the RTC on power-up. Any writes to the

RTC also update the TOY clock.

4.5.8

Two-wire serial bus interface, SBCon

The IO FPGA implements two custom two-wire serial bus interfaces, SBCon 0 and SBCon 1.

SBCon 0 provides access to the PCIe interface on the motherboard.

SBCon 1 provides access to the

Digital Data Channel

(DDC) of the external display connected

to the DVI connector on the rear panel.

The internal registers of the two-wire serial bus interface are memory-mapped onto a static
memory bus chip select. The chip select that they map onto depends on the memory map your
daughterboard is using as follows:

•

ARM legacy memory map:
—

The registers map onto the CS7 chip select.

•

Cortex-A Series

memory map:

—

The registers map onto the CS3 chip select.

Note

See the Technical Reference Manual for your daughterboard.
