Calibration bus interface

The calibration bus is made up of address bus, data bus, and bus control signals, and is

used on the calibration board to access the upon board memory.

The

calibration board supports a 16-bit de-mulitplexed calibration bus. This is derived from

the multiplexed bus on the SPC563M64xx, where the majority of address lines are derived

from the data lines (CAL_DATA on SPC563M64 device), by using an onboard external latch

controlled by the C_TS signal. The ALE functionality of this signal indicates to the external

latch when to capture the address signals
