NOICE OPERATION
NOICE is a development software provided by
development environment that is supported by the NOICE host PC software. This
development environment has the capability to provide symbolic debug for C source codes
and compilers for a low cost. A fully functional software version is available on the support CD
that will operate in demonstration mode. The user should register the software and download
the latest version from the above web site to get full support. See the NOICE documentation
for details.
The CML12S-DP256 provides the NOICE debug monitor kernel as a subset of the MON12
monitor in reserved flash memory. User may apply the NOICE development system by setting
the MON12 Autostart for the $F800 vector, reset the board and launch the NOICE host
software on the PC. The NOICE monitor kernel applies the same resources, memory map,
and ram interrupt table as the MON12 monitor. NOICE operation notes:
Baud Rate
= 19.2K baud 8/n/1
E clock frequency
= 24MHz
