Hi, Now I want to use monitor with RDC-8052TTE(http://www.rdc.com.tw) but got a troublesome problem. Because the RAM bus and ROM bus are seperated in this MCU and the PSEN# signal is always low, I am confused how to layout the schematic. Does monitor can co-operate with this MCU? 1. Because the PSEN# always low, the bus will contention during fetch code, right? (ROM and von Neumann RAM will output data at the same time) 2. Should I connect von Neumann memory in RAM bus or ROM bus?
