H A D | lpc1850-cgu.txt | 1 * NXP LPC1850 Clock Generation Unit (CGU) 3 The CGU generates multiple independent clocks for the core and the 4 peripheral blocks of the LPC18xx. Each independent clock is called 5 a base clock and itself is one of the inputs to the two Clock 9 The CGU selects the inputs to the clock generators from multiple 10 clock sources, controls the clock generation, and routes the outputs 11 of the clock generators through the clock source bus to the output 12 stages. Each output stage provides an independent clock source and 13 corresponds to one of the base clocks for the LPC18xx. 15 - Above text taken from NXP LPC1850 User Manual. [all …]
