Using the Debugger

Note that on a restoration context switch, registers whose
perspectives feature MMU characteristics and operating modes of
the MPU are not restored. The debugger honors the user's MMU
configuration. If the user's program wishes to utilize the
programmatic interface (i.e., system calls) of the debugger, it must
maintain the address translation of 1 to 1, and the I/O resources
utilized by the debugger must be data cache inhibited.
Floating Point Support
The MD and MM commands allow display and modification of
floating point data in memory. Use either the MD command or the
MM command to assemble or disassemble floating point
instructions.
Valid data types that can be used when modifying a floating point
data register or a floating point memory location:
When entering data in single or double precision format, observe
the following rules:
❏ The sign field is the first field and is a binary field.
❏ The exponent field is the second field and is a hexadecimal
field.
❏ The mantissa field is the last field and is a hexadecimal field.
