Hi,

The LPC1100 and LPC1300 do not support JTAG for debug. They are both SWD-only.

Hello,

what option will be selected on IOCON_JTAG_TDI_PIO0_11.FUNC = 0? When documentation update will be available?
Thanks.

Func 000 on pin PIO0_11 is not supported because the LPC111x and LPC134x do not support JTAG. The Users Manual will be updated to reflect this.
