AT89C51ED2 Reset pin is latched up to high state

Dear Friend, I am using a 64 pin VQFP AT89C51ED2 which has been mounted on a VQFP to DIP pcb. I observe at power up, the reset pin is latched up to high state. Wiring conditions are :Vcc=5V, Gnd, EA...

Cortex-M0+ JTAG state doesn't reset in simulation when tying nTRST high and trying synchronously reset through TMS

Hi, According to the Cortex M0+ integration guide: "nTRST can be tied HIGH when a synchronous JTAG reset is provided through the TMS pin." However in simulation the JTAG state is constant 'X' and...
