Debugger Pinout for LPC1113

Greetings,

Just got my first board with a LPC1113 working with LPC Link, took me a day to find out that the 3.3V regulator was dead, and there I was looking at the signals from the debugger!

Anyway, I need some advice on the proper connection of the debug signals to the 10 way header on the LPC Link. This is what I have:

1: 3.3V via 0R link.
2: SWDIO
3, 5, 9: 0V
4: SWCLK
6, 7, 8 No Connection
10: /RESET

I have a 10K pullup resistor on /RESET, but no pullups on SWDIO or SWCLK. I was intending to disable debug in released code by setting CRP level 1 & setting these pins to output, so removing the issue of noise pickup on the debug pins.

Do I have this right?

You only need SWDIO, SWCLK, RESET and GND for a functioning SWD debug on the LPC1113

Actually I have never seen the LPC-Link assert RESET, maybe it only does so if there is no response to data on SWDIO/SWDCLK. I should check this.

Certainly there is no need for any connection to pin 1 for the LPC Link, as it only has a "not fitted" resistor on this pin. Maybe it is required for the bigger debuggers.
