OTHER HARDWARE CONSIDERATIONS
To facilitate in-circuit programming, plus in-circuit debug and
emulation options, users will want to implement some simple
connection points in their hardware to allow easy access to
download, debug, and emulation modes.
In-Circuit Serial Download Access
Nearly all ADuC841/ADuC842/ADuC843 designs want to take
advantage of the in-circuit reprogrammability of the chip. This
is accomplished by a connection to the ADuC841/ADuC842/
ADuC843’s UART, which requires an external RS-232 chip for
level translation if downloading code from a PC. Basic configura-
tion of an RS-232 connection is illustrated in Figure 85 with a
simple ADM202 based circuit. If users would rather not design
an RS-232 chip onto a board, refer to Application Note uC006, A
4-Wire UART-to-PC Interface, (at www.analog.com/microconverter)
for a simple (and zero-cost-per-board) method of gaining in-
circuit serial download access to the part.
In addition to the basic UART connections, users also need a
way to trigger the chip into download mode. This is accom-
plished via a 1 k pull-down resistor that can be jumpered onto
the PSEN pin, as shown in Figure 85. To get the part into download
mode, simply connect this jumper and power-cycle the device
(or manually reset the device, if a manual reset button is available),
and it will be ready to serially receive a new program. With the
jumper removed, the device comes up in normal mode (and
runs the program) whenever power is cycled or RESET is toggled.
