Description
0 - Indicates if the enabled clock is running
1 - Indicates that the clock is being blocked during a frequency
change to avoid glitches
00: clk_mem = PLL2
01: clk_mem = PLL2
10: clk_mem = 27 MHz xtal_clk
11: clk_mem = GPIO[7]
1: enable clk_mem
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
0 - Indicates if the enabled clock is running
1 - Indicates that the clock is being blocked during a frequency
change to avoid glitches

0 - Indicates if the enabled clock is running
1 - Indicates that the clock is being blocked during a frequency
change to avoid glitches
00: clk_pci = 27 MHz xtal_clk
01: clk_pci = clk_33
10: clk_pci = xtal_clk/16 = 1.68 MHz
