Stack 32

Type Function module

Input DIN	DWORD (data input)
E	BOOL (enable input)
RD	BOOL (read command)
WD	BOOL (write command)
RST	BOOL (Reset input)
Output DOUT	DWORD (data output)
EMPTY	BOOL (EMPTY = TRUE means that memory is empty)
FULL	BOOL (FULL = TRUE means: memory is full)
	STACK_32 is a stack (STACK) with 32 memory locations for DWORD data. The two outputs EMPTY and FULL indicate when the memory is full or empty. The RST input clears the entire contents of the memory. The FIFO is set with DIN, by setting a TRUE to the input WD, and true to the input E. A read command is executed by TRUE to RD and TRUE to E. Reading and writing can be performed simultaneously in one cycle. The module reads or writes in each cycle as long as the corresponding command (RD, WD) is set to TRUE.
