Description
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: clk_ai_sck = 27 MHz xtal_clk
1: clk_ai_sck = AI_SCK pin
1: enable clk_ai_sck
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
00: ao_osclk = 27 MHz xtal_clk
01: ao_osclk = DDS3
10: ao_osclk = PLL1
11: ao_osclk = XIO_D[14]
