The debug signals are multiplexed with general purpose I/O pins, so some signals will
require proper biasing to select the operating mode. The JTAG_TMS signal on PTA3
requires a strong pullup resistor for mode selection. The Cortex Debug specification
recommends that the JTAG_TCLK and JTAG_TDI pins (on PTA0 and PTA1) have pull
resistors (high or low) to force a known state on these debug input pins. Note that the
RESET_b signal in the debug interface is the MCU’s reset pin and not the JTAG_TRST
signal. The connectors for this interface are keyed dual row 0.050” centered headers.
When implementing either of these headers on a target system, pin 7 must be depopulated
to use the 19-pin or 9-pin adapters from the debug tool. The Samtec part numbers for
these connectors are:
