Dear Sir,
we are using LPC4367 MCU in our design. It was observed that the MCU was getting locked and we need to erase it again to work on it.
While comparing with the reference schematic LPCXpresso43/18xx v3 Rev B, we found that the pin connected to JTAG programming is having different pullups.
IF_TDO_SWO: 100K pullup
IF_TMS_SWDIO: 100K pull up
IF_RST: 100K pull up
TCK-SWDCLK_TRGT: 2.2K pullup
IF_JTAG_TDI: No pull up
In my design we have used fixed 10K pull up. Can you please explain why different pullup are needed and what is the use of NX3DV2567GU,115 Analog switch.
Thanks
Manish Sharma
