DEVELOPMENT SUPPORT
The CSM12C32 ships from the factory with a serial monitor installed in FLASH. An ASCII
monitor is also installed to provide quick and easy debug access to the user. The text monitor
is available out of RESET. The serial monitor is available by pressing and holding SW1 as the
module exits RESET. In the discussion below, the terms text and ASCII are used inter-
changeably.
ASCII Monitor Operation
The debug monitor provides a simple application development platform for developing applica-
tion code. The debug monitor allows the user to quickly and easily develop and debug RAM
based application code.
The debug monitor is accessible through the COM port using an ASCII terminal program such
as HyperTerminal or AxIDE. The terminal should be configured for 9600, 8, N, 1 with no flow-
control. The monitor relocates the hardware interrupt vector table from 0xFF8A:0xFFFF to
0X0F8A:0x0FFF. Table 3 below shows the memory map applied when the Monitor is active.
The vectors remain in the same order as the default hardware table. The Reset vector is re-
served; user should use autostart to start applications from reset.
