HDI Parameter
(Trace Display) Address Area Description
rom On-chip ROM MCU's on-chip ROM, which can be
read but cannot be written to.
ram On-chip RAM MCU's on-chip RAM (except for DTC
RAM), which can be read and written
to.
IO16
(I/O-16)
Internal I/O registers
(16-bit bus)
MCU's internal I/O registers for the 16-
bit bus.
IO8
(I/O-8)
Internal I/O registers
(8-bit bus)
MCU's internal I/O registers for the
8-bit bus.
ext16
(EXT-16)
External area
(16-bit bus)
External area for the 16-bit bus, which
can be allocated to the user system
memory or the optional SIMM memory
module in the E6000.
ext8
(EXT-8)
External area
(8-bit bus)
External area for the 8-bit bus, which
can be allocated to the user system
memory or the optional SIMM memory
module in the E6000.*
Dtcram
(RAM/DTC)
