Description
00: clk_lan = 27 MHz xtal_clk
01: clk_lan = clk_lan_src
10: clk_lan = 27 MHz xtal_clk
11: clk_lan = AO_SD[0]
1: enable clk_lan
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: clk_lan_rx = 27 MHz xtal_clk
01: clk_lan_rx = CLK_LAN_RX pin
10: clk_lan_rx = 27 MHz xtal_clk
11: clk_lan_rx = CLK_LAN_RX pin
1: enable clk_lan_rx
To ensure software backward compatibility unused or reserved bits
