WebThe WRITE STATUS REGISTER commands can also be used also to program the status register write enable/disable bit of the status register. If the W# pin is held LOW (to VIL) and the status register write enable/disable bit in the status register is set (i.e., programmed to 1), the status register nonvolatile bits become WebFeb 5, 2014 · Register Design in VHDL. I'm having some troubles in designing a 1-bit and 32-bit register in VHDL. Main inputs of the register include clock (clk), clear (clr), load/enable (ld) signals and an n-bit data (d). The n-bit output is denoted by (q). So far I believe to have made a 1-bit register, here is my code:
WebNov 14, 2013 · 8. I am trying to write a register file in VHDL. The file contains 16 64-bit registers.
