Description
00: clk_gpio_q6_12_ctl = 27 MHz xtal_clk
01: clk_gpio_q6_12_ctl = DDS6
10: clk_gpio_q6_12_ctl = 27 MHz xtal_clk
11: clk_gpio_q6_12_ctl = LAN_TXD[3]
1: enable clk_gpio_q6_12_ctl
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_13_ctl = 27 MHz xtal_clk
01: clk_gpio_13_ctl = DDS5
10: clk_gpio_13_ctl = UNDEF
11: clk_gpio_13_ctl = LAN_RXD[0]
1: enable clk_gpio_13_ctl
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_14_ctl = 27 MHz xtal_clk
01: clk_gpio_14_ctl = DDS2
10: clk_gpio_14_ctl = UNDEF
11: clk_gpio_14_ctl = LAN_RXD[1]
1: enable clk_gpio_14_ctl
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
Invert FGPO clock
0 : do not invert the clock
1: invert the clock only to the fgpo block and not to the pad.
FGPO output select
0: Seperate output mode, The clock to the fgpo and to the pad
share the same source, but have seperate paths.
1: Feedback output mode, The clock is driven to the pad then is
feedback to the clock block. It then goes through gating logic to the
fgpo block.
