Because of an design fault, we have wired the CLK input of a SPI like sub-chip with SWCLK pin (PIO0_10) of an LPC1343 Cortex-M3. This prevents from debugging this SPI like interface and the sub-chip output etc. Beside cutting and manually wiring the CLK input to another output of µC: Is it possible to switch pin function by software? Like - switch pin function of PIO0_10 to GPIO - do SPI like CLK and DATA for the sub-chip - switch pin function of PIO0_10 back to SWCLK. Will ULINK Pro tolerate that? Best regards Juergen Marquardt
>>Will ULINK Pro tolerate that?
I'd doubt it.
