Analog testmode bit. Drives value on the DM pad. Default value is 1'b0. This bit came from the test control
module.
Analog testmode bit. Set to 0 for normal operation. Set to 1 for engineering debug of analog PHY block.
This bit came from the test control module.
Reserved.
If set to 0, 9-phase PLL outputs for USB PHY are powered down. If set to 1, 9-phase PLL outputs for USB
PHY are powered up. Additionally, the UTMICLK120_GATE and UTMICLK30_GATE must be deasserted
in the UTMI phy to enable USB operation. This bit came from the clkctrl PIO control block
(clkctrl_pllctrl0_en_usb_clks).
Software controlled bit to indicate when the USB PLL has locked. Software needs to wait 10 us after enabling
the PLL POWER bit (0) before asserting this bit. If set to 0, tells the UTMI module that the USB PLL has not
locked. If set to 1, tells the UTMI module that the USB PLL has locked. Software should clear this bit prior
to turning off the USB PLL. This bit came from the clkctrl module.
USB PLL Power On (0 = PLL off; 1 = PLL On). Allow 10 us after turning the PLL on before using the PLL
as a clock source. This is the time the PLL takes to lock to 480 MHz. This bit came from the clkctrl PIO
control block (clkctrl_pllctrl0_power).
