#23349 - state of the RD pin during fetches
Hi everybody!
I'm designing a project with a romless 8052 using external eeprom and sram (2 separate chips), and eeprom contains code (0000h-8000h) plus data (8001h-FFFFh)
I interfaced the two chips, but a question arose in my mind: during fetches to external code, the RD pin (37) goes low or remains high?
this is because I need to have G/ of eeprom low to read form the device

Best regards,
teo.
