1.17 Documentation Note
The terms S12P, S12X , S12HY,S12XHY and S12S which appear in some of the following chapters refer
to the original architecture which those modules were designed to work with. Please do not confuse them
with the S12XHY product families.
S12XHY will support only 10-bit ATD resolution, although in ATD12B block it still has the 12-bit
descriptions.
SSD block says one SSD can be configed to control two motors, while in chip level, this feature is not
supported.
