Program – program user function memory
The Program command is used to program the user function memory. Once in program mode, the uM-FPU looks for
valid Intel Hex format records. The records must have an address between 0x0000 and 0x03C0, start on a 64-byte
boundary, and have a length of 1 to 64 bytes. The data is not echoed, but an acknowledge character is sent after each
record. The acknowledge characters are as follows:
The uM-FPU IDE program (or another PC based application program) would normally be used to send the required
data for the program command. (See documentation for the uM-FPU IDE application program.) To exit the program
mode, an escape character
is sent. The program command will reset the uM-FPU on exit.
Debug Opcodes
There are several opcodes that are designed to work in conjunction with the debug monitor. If the serial debug
monitor interface was not selected by the TSTIN pin at the last Reset, these commands are NOPs. The opcodes are
as follows:
BREAK
When this opcode is encountered a Break occurs and the debug monitor is entered. Execution will only resume when
a Go command is issued to the debug monitor.
TRACEOFF
Turns the debug trace mode off.
TRACEON
Turns the debug trace mode on. All opcodes will be traced on the debug terminal until the trace mode is turned off
by a TRACEOFF opcode or is turned off using the debug monitor.
TRACESTR
Displays a trace string to the debug monitor output. This can be useful for keeping track of a debug session. Trace
strings are always output; they are not affected by the trace mode.
