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.
