 10-pin 2.54mm Renesas 78K0 Serial Cable Adapter
This adapter is used to connect the iC5000 / iC5500 / iC6000 development system to Renesas 78K0 based target
via Serial debug interface. It connects to Debug/Trace module on one side and to the target debug connector on
the other side. It can be used for targets featuring 10-pin 2.54 pitch target debug connector with 78K0 pinout.
The following pinout is valid on the target side:

If the 'Supply 5V to the target' option is checked in the 'Hardware/Emulation Options/CPU Setup/Advanced'
tab, the debugger supplies 5V at 5V OUT pin (pin 10) of the target debug connector, which can be used to
power the target. Maximum target current consumption should not exceed 50mA.
Note: 10-pin Renesas 78K0R Serial Debug Cable Adapter features resettable fuses on all connected pins. These
protect debug signals against overcurrent and cycle back to a conductive state after the excessive current fades
away.
If 'RESET IN' (target reset detection) is not connected to the target debug connector, make sure that 10k pull up
is connected to this pin (target debug connector pin 1) or the debugger may exhibit unpredictable behavior.
The adapter connects to the target via a 10-pin 2.54 mm connector (for example Yamaichi: FAS-1001-2101-2-
OBF). A target should feature a matching part (for example WÜRTH ELEKTRONIK: 612 010 216 21).
An additional adapter (ordering code IAPIN10PIN16NEC78K) must be ordered separately in order to connect to
a target featuring 16-pin 2.54 pitch target debug connector.
