Description
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_spdi_src = clk_144
1: clk_spdi_src = clk_72
00: clk_spdi = 27 MHz xtal_clk
01: clk_spdi = clk_spdi_src
10: clk_spdi = UNDEF
11: clk_spdi = LAN_TXD[0]
1: enable clk_spdi
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_gpio_q4_ctl = 27 MHz xtal_clk
01: clk_gpio_q4_ctl = DDS8
10: clk_gpio_q4_ctl = 27 MHz xtal_clk
11: clk_gpio_q4_ctl = LAN_TXD[1]
1: enable clk_gpio_q4_ctl
To ensure software backward compatibility unused or reserved bits
must be written as zeros and ignored upon read.
