There are a number of RXD and TXD pins available on the LPC1115FBD48 variant listed below,

RXD - Pin 46, 37, 18, 11
TXD - Pin 47, 36, 21, 12

My question is what pin/pair will be used during the initial bootup ISP programming.  In the LPC1114, there is only one RXD and TXD pin option.

I have gone through the manual and datasheet and this is not stated clearly what pins are used for the ISP programming bootloader.

Thanks for your help,
