On board JTAG connector[edit | edit source]

TBD: sostituire con le informazioni del connettore e del pinout

JTAG signals are routed to a dedicated connector on the MITO 8M PCB.

The connector is placed on the top side of the PCB, at the upper-right corner (please see the picture below).

JD5 - Connector's pinout[edit | edit source]

On the JF5 footprint can be hand soldered a header pinstrip 10x1x1.27mm connector. The following table reports the connector's pinout:

Pin# Pin name Function Notes
1 DGND -
2 EEPROM_WP -
3 NC -
4 JTAG_TCK - internal pull-up 10k to NVCC_3V3
5 JTAG_TMS -
6 JTAG_TDO -
7 JTAG_TDI -
8 JTAG_nTRST -
9 CPU_PORn - internal pull-up 100k to NVCC_SNVS
10 NVCC_3V3 - reference voltage for JTAG signals
