Hello, I need some help regarding the 68HC11E1 processor external memory interface. We are using the 614 KHz clock frequency and are using the processor custom chip which doesn't have internal program memory. We have tied the MODA and MODB pins to VCC thru pull-up resistors. The reset is thru external monitor chip.And we have interfaced flash as
