The chip is controlled with three pins; WR, OE, and CS. Before we jump into physically building the computer, as well as construct a memory programmer, we will first quickly go over key details from the previous articles to refresh our memory (pun intended). The OE pin is used to read data from the chip, and the CS pin is used to select the memory chip itself. "margin-left": "0px", To get the content into the ROM I added a simple serial protocol to the TGL-6502 firmware but as the firmware grew this functionality had to be dropped to free up some of the limited flash memory so I had to find an alternative method.
