Verilog HDL beginner question!
[table][tr][td]In Verilog HDL, when defining the reg register type, it is defined like this, reg [msb: lsb] reg1, reg2, . . . reg N; msb and lsb define the range and are both constant value expression
Let's see if there is any problem with the program I wrote for M25P40? I just can't read the FLASH ID, I'm so depressed
My program is made on LPC2146. I also checked it with an oscilloscope. The commands, timing and chip select issued by MOSI are all fine, but MISO doesn't send anything back. I'll post the program to h
