XCLK on lpc2294

XCLK on lpc2294

2005-09-26 by altlen

I am trying to activate XCLK on lpc2294 pin 40 (P3.23). I use the 
following setup:

PLLCON - 0x3
PLLCFG - 0x25
PLLSTAT - 0x725

VPBDIV - 0

PINSEL2 - 0x0C6169E4 (addr A2-A19, CS2, CS3, XCLK - ON).

The status registers confirm this setting, however, I can't see XCLK.

I will appreciate any suggestions,

Leon

You might have to set the direction bit for that particular pin to output.

Thank you for the suggestion. The direction is selected automatically 
for non-GPIO pins according to the documentation. However, I tried 
anyway and it didn't help.
