Hi friends, i have a doubt in pin multiplexing of lpc3250. I want to use U1_RX (K15) pin. How to set it?
pin details are given down.
K15(pin) - U1_RX / CAP1[0] / GPI_15 (functions)
In pin multiplexing section this is not mentioned. Is it noted any where else? i want to use all uart pins like K17,K18,J14,F18,F17.
See: http://www.keil.com/forum/17653/ - this is really a question for NXP; nothing to do with Keil
GPI_15 is on P3.15.
The multiplexing of this pin is controlled via P3_MUX_SET, P3_MUX_CLR and P3_MUX_STATE.
The P3_MUX_ registers are nicely documented in chapter 33 of the LPC32x0 and LPC32x0/01 User manual.
