TDI	7	8	VCC
TMS	9	10	(FLMD2)
RDY-	11	12	GND
RESET-	13	14	GND

Note: Signals FLMD1 and FLMD2 are optional. This pin assignment is supported by debug-cables:

LA-3719 Debugger for RH850/V850 (ICD)
LA-3205 Debugger for RH850/V850 AUTO26 (PACK) plus adaptation LA-2700 Conv. AUTO26 to JTAG14 RH850

Connector Type

This is a standard 14 pin double row (two rows of 7 pins) connector (pin to pin spacing: 2.54mm/0.100").
If terminal strip without shroud is used, the spacing marked with "A" must be a minimum of 23mm/0.9".

Signal recommendations for Mictor 38-pin

Signals in brackets are optional. These could be used if no additional 14 pin debug connector is available on the target. Please use an adaptor (LA-3885) to split the target signals for debug and trace.
