talker to transmit the required bytes of MCU memory to Xplor8 where they will be stored in the

corresponding address locations in the local memory array. From there they will be displayed in the

output window.

It should be noted that it is certainly not the case that the local memory is always a faithful copy of the

MCU controlled memory. In fact, at start-up, the Xplor8 local memory is initially filled with zeros.

Only as a result of commands such as L (List) will t he local memory become a copy of the MCU

memory. Also, commands which load the MCU with data, such as the command to load an S19 file,

do so via the local memory, so making the local and MCU memories identical over the range of

addresses covered by the loaded file.

Many commands have a version that affects only the local memory, for example 'LDL' - see Load

Memory on page 51.

2.9 USB-to-Serial Adapters

Many USB-to-serial adaptors will not work satisfactorily with Xplor8 (or with other PC host

programs). This is because they do not recognize the 'break' character emitted by the MCU when it

enters Monitor Mode. As recognition of this break is critical to the operation of the host PC, such

adaptors are useless.

However, adaptors based on the FTDI chipset appear to work just fine. The author uses a
