Description
Address Lines
Chip Enable
Output Enable
Read/Write Enable
Semaphore Enable. When asserted LOW, allows access to eight semaphores. The
three least significant bits of the address lines will determine which semaphore to write
or read. The I/O0 pin is used when writing to a semaphore. Semaphores are requested
by writing a 0 into the respective location.
