The eZ80190 MCU features 8 KB of internal SRAM in the address range

E000h

FFFFh

and 1 KB of MACC RAM in the address range

DC00h

DFFFh

. Internal RAM can be mapped anywhere in the 16 MB address

space in 64 KB steps (

DC00h

FFFFh

to

DC00h

FFFFFFh

). The software

included in the eZ80190 Development Kit assumes internal RAM in the
range

E000h

FFFFh

for the interrupt vector table. This range overlaps the

address range assigned to Flash memory (CS0) on the eZ80190 Module.

The Ethernet controller, located on the eZ80190 Module, is mapped as an
I/O device at address

300h

. It uses CS3.
