All registers can be asynchronously cleared by ESB local interconnect signals, global signals, or the chip-wide reset.
APEX 20KE devices have four dedicated clocks.

Content-Addressable Memory
In APEX 20KE devices, the ESB can implement CAM. CAM can be
thought of as the inverse of RAM. When read, RAM outputs the data for
a given address. Conversely, CAM outputs an address for a given data
word. For example, if the data FA12 is stored in address 14, the CAM
outputs 14 when FA12 is driven into it.
CAM is used for high-speed search operations. When searching for data
within a RAM block, the search is performed serially. Thus, finding a
particular data word can take many cycles. CAM searches all addresses in
parallel and outputs the address storing a particular word. When a match
is found, a match flag is set high.
