DMM OPENGUI command
Syntax
DMM OPENGUI [mcuid]
with <mcuid>, a part/device MCUID value in range $0-$FFFF.
Purpose
Opens the DMM Graphical User Interface. Note that the MCUID parameter is not
mandatory.
DMM SETAHEADREADSIZE command
Syntax
DMM SEATAHEADREADSIZE <front size when halted> <back size
when halted> <front size when running> <back size when
running>
with:
<front size when halted> : amount of bytes to read ahead of exact start of
read block address, when the hardware is halted.
<back size when halted> : amount of bytes to read after the exact block of
read addresses, when the hardware is halted.
<front size when running> : amount of bytes to read ahead of exact start
of read block address, when the hardware is running.
<back size when running> : amount of bytes to read after the exact block
of read addresses, when the hardware is running.
Purpose
Special debugger memory cache tuning in case of slow connection with hardware.
