BL160024 s BL1600 Operation
Operating Modes
A hardware reset takes place when the BL1600 is powered up, when a
reset is done manually by connecting pins 910 on header H4, or when the
watchdog timer times out.
If a valid program (created with Dynamic C) has been installed in
EPROM, the program starts running. A valid program is recognized by a
code that Dynamic C places in the file used to burn the EPROM.
The flowchart in Figure 3-1 shows the startup sequence of the BL1600
after a hardware reset.
