All registers shown except the rden register have asynchronous clear ports.
Violating the setup or hold time on the address registers could corrupt the memory contents. This applies to both
read and write operations.

2–20:
Read/Write Clock Mode
The M4K memory blocks implement read/write clock mode for simple
dual-port memory. You can use up to two clocks in this mode. The write
clock controls the block's data inputs, wraddress, and wren. The read
clock controls the data output, rdaddress, and rden. The memory
blocks support independent clock enables for each clock and
asynchronous clear signals for the read- and write-side registers.
