Hi, I am designing a peripheral interface IO chip which is also the Intel i82C55 chip. THe problem I have is I want to change a interrupt signal INTR to '1' at the rising edge of a strobe input (STB) and then later change INTR to '0' when the read signal (RD) arrives (at the rising edge of RD). My VHDL code is
handshaking: process(STB, RD) is begin if rising_edge(STB) then INTR
