Using the Onboard Serial Programming
Mode
The serial programming mode is primarily used to program the flash ROM in
devices that are already installed on a PCB board. Panasonic provides the ded-
icated hardware and software for this mode. This section describes the microcon-
troller hardware, system configuration, software register map, and protocol for
this type of programming operation.
