Good day, every one:
I want to change the register value about Clock Symbol and Transmitter Control(HDMI_PHY_CKSYTXCTRL).
and have been read these:
pdf A : "i.MX 6Dual 6Quad Applications Processor Reference Manual" rev. 1
pdf B : "i.MX 6 Series HDMI Test Method for Eye Pattern and Electrical Characteristics"
and I can not understand the meaning about 15th bit (Override) at pdf A, page 1821.
the description is all blank, I think this bit may just the same as pdf A, page 1811:
"If the Override bit is set to 1, the working value is the Override bit value, not the registered value."
* so if I set override bit to "1", all other bits will force to "1"? *
a example in pdf B, page 6. teach me how to set register HDMI_PHY_CKSYTXCTRL(register 0x09) for value 0x800Dh.
why I need set the override bit to "1"? does it also work if I set register 0x09 to 0x000Dh?
any hint or explanation wolud be appreciated, thanks.
