4 POWER MANAGEMENT
4-27
4.7.1 USB OTG PHY
USB OTG PHY has three power modes, namely, Run, IDLE, and Suspend mode.
•
In Run mode, USB OTG PHY sends and receives data normally.
•
In IDLE mode, there is no data transaction to and from USB OTG PHY. However, the clock is still supplied to
USB OTG PHY.
•
In Suspend mode, USB OTG PHY clock is “OFF” to save power.
In NORMAL mode, all the three power modes can be used.
If USB OTG PHY is in use, then it is in Run mode when there is data transaction, and in IDLE mode when there is
no data transaction. The USB OTG link performs the change between these two modes.
If USB OTG PHY is not in use, then it can enter into Suspend mode. Set register in USB OTG for Entry to, and
Exit from Suspend mode.
In IDLE mode and DEEP-IDLE mode where TOP block is ”ON”, USB OTG PHY keeps its operation or power state
in NORMAL.
Before entry to DEEP-IDLE mode where TOP block is ”OFF”, STOP, DEEP-STOP, and SLEEP mode, it is
recommended that USB OTG PHY enter into Suspend mode.
4.7.2 HDMI PHY
HDMI PHY has two power modes, namely, Run and Power-down mode
•
In Run mode, HDMI PHY sends and receives data normally.
•
In Power-down mode, all power to HDMI PHY is “OFF” internally.
In NORMAL mode, both the power modes can be used.
If you want to use HDMI PHY, then set it in the Run mode. Otherwise, it can enter into Power-down mode to save
static power by setting register in HDMI link. I2C I/F can control the mode transition from normal mode to power-
down mode. The hardware signal, PWR_OFF, is not used for this purpose.
In IDLE mode, and DEEP-IDLE mode where TOP block is ”ON”, HDMI PHY keeps its operation or power state in
NORMAL.
Before entry to DEEP-IDLE mode where TOP block is ”OFF”, STOP, DEEP-STOP, and SLEEP mode, it is
recommended that HDMI PHY enter into Power-down mode.
