RO

This bit indicates the status of programming of the display 

PLL and the selected display port. This a power on cycle will not be allowed unless this 

status indicates that the required assets are programmed and ready for use. 

0 = All required assets are not properly programmed. 

1 = All required assets are ready for the driving of a panel. 

The following conditions determine that the assets are ready: 

1) Display Pipe PLL Enabled and frequency locked (bit-31 of DPLL Control Register for 

the pipe attached to the embedded panel port). 

2) Display Pipe Enabled (bit-31 of PIPECONF Pipe Configuration Register. For the pipe 

attached to the embedded panel port) 

3) Embedded Panel Port is Programmed Enabled

00 = Indicates that the panel is not in a power 

sequence 

01 = Indicates that the panel is in a power up sequence (may include power cycle delay) 

10 = Indicates that the panel is in a power down sequence 

11 = Reserved

RO

Power cycle delays occur after a panel power down 

sequence or after a hardware reset. On reset, a power cycle delay will occur using the 

default value for the timing. 

0 = A power cycle delay is not currently active 

1 = A power cycle delay (T4) is currently active
