10:8 | SCP_PWR_DIV | Defines the divisor value to be used for the generation of the SCP_PWR clock (up to 66.5MHz) from the input interface clock (up to 266MHz). 0x0 means gated 0x1 means free-running The valid values are from 0 to 7. In case of interface access to register through SCP interface, if the SCP_PWR clock is gated, the HW automatically generates the clock by using a divisor of 7 and updates the bit-field with the value 7. It is then software responsibility to change the value at any time in order to improve SCP latency when accessing the registers in the HDMI_PHY and PLLCTRL_HDMI by reducing the value. | RW | 0x0 |
