6. Target Hardware Connectivity for In-System Programming
This section describes the hardware connections to the ICD for in-system programming purposes.
Examples for different M16C MCU’s are shown at the end of the section.
The ICD connects to an M16C target board through a polarized, .100” (2.54mm), 10-pin connection using
a flat ribbon cable. It communicates with the M16C MCU using the boot UART/SIO in a clocked SIO
configuration. The signals used and how these signals are assigned is described below.
NOTE:
All target interface lines are in high impedance state until instructed to do otherwise by the FoUSB
Programmer application.
This provides the common connection point for power between ICD and the target board. This must be
connected to the target board’s Vcc line/plane.
In Target Power mode, the ICD requires at least 3.3V (5.0V max) and 50mA to operate properly.
When programming target boards other than Renesas SKPs, set S1 to Target Powered mode and supply
external power.
This line indicates whether the target is busy (and cannot receive data) or not. This must be connected to
the target MCU’s boot UART/SIO BUSY (CTS/RTS) pin.
This pin may be used for other applications as long as the user ensures that the ICD can drive the pin to
valid levels with 5mA current.
This clock is used for synchronous serial communication between ICD and target board. This must be
connected to the target MCU’s boot UART/SIO SCLK pin.
This pin may be used for other applications as long as the user ensures that the ICD can drive the pin to
valid levels with 5mA current.
This is the ICD SIO transmit data output. This must be connected to the target MCU’s boot UART/SIO
receive data input (RXD) pin.
This pin may be used for other applications as long as the user ensures that the ICD can drive the pin to
valid levels with 5mA current.
