Read/Write Clock Mode
The read/write clock mode contains two clocks. One clock controls all
registers associated with writing: data input, WE, and write address. The
other clock controls all registers associated with reading: read enable
(RE), read address, and data output. The ESB also supports clock enable
and asynchronous clear signals; these signals also control the read and
write registers independently. Read/write clock mode is commonly used
for applications where reads and writes occur at different system
frequencies. Figure 20 shows the ESB in read/write clock mode.

Notes:
(1)
All registers can be cleared asynchronously by ESB local interconnect signals, global signals, or the chip-wide reset.
(2)
APEX 20KE devices have four dedicated clocks.
