microsystems µFlashTCP-EP User’s Manual Hardware Memory Configuration The 386Ex processor is initially configured in real mode with a physical address space of 1 megabyte. The SRAM is located between 00000h and 7FFFFh, the flash is between 80000h and FFFFFh. A 32-pin DIP socket is provided for additional flash, RAM, or EPROM. This memory can be accessed by reprogramming the chip select unit in the 386Ex or by entering protected mode. -

The data on Port 3 can be read from I/O address F870 hex. The pins default to inputs. Each bit of Port 3 can be individually configured as an input or output. - Page 13 microsystems µFlashTCP-EP User’s Manual COM1 is wired as Data Terminal Equipment (DTE) for connection to a peripheral such as a modem. This is a full function RS-232 port implementing all of the handshaking and control lines with the exception of the Ring Indicator input. The UART base address is at I/O location 3F8h and can be configured to use IRQ 4.
