Hi,
I am using an LPC1114 and wanting to use a SSP bus master to obtain 24 bits in two 12 bit transactions, at 32KHz intervals. The master clock will be about 48MHz I will be setting the busmaster to set SSP clock to 5MHz. Is it possiable to use an interupt to service this, or would the serviceing of the interupt take a significant part of 2.4us and so not worth it?
Thanks
