I am using LPC1857 device kit.
And there are 4 pins named CLK0, CLK1, CLK2, CLK3 on board.
In software i am using CMISIS and based on that i am getting default frequency 12MHZ. PLL range is from 0 - 15, so i can say that i can get frequency from 12 MHZ, 24MHz, 36MHz, ... , 180MHz.
PROBLEM : By default i am getting 12MHz from CLK1 pin by writing this below code.
"LPC_SCU_CLK(1) = 1 + CLK_OUT;"
And I want 6MHz from LPC18xx, Can you help me to set 6MHz on CLKOUT pin?
