Pixel Clock Enable - Read/Write
The value written to this bit selects whether the pixel clock
or smart panel clock are output to the SPCLK pin, or not:
0 - SPCLK pin at high impedance
1 - PCLK or SCLK active on SPCLK pin
The PIFEN bit above selects PCLK vs. SCLK.
Enable Video State Machine - Read/Write
The value written to this bit selects whether the video state
machine is enabled, or not:
0 - Video state machine off
1 - Video state machine enabled
Reserved - Unknown during read
Software Lock - Read/Write
WRITE: Writing 0X0000_00AA to this register will unlock
all locked registers until the next block access.
READ: During a read operation, SWLCK[0] has this
meaning:
1 - Unlocked for current bus access
0 - Locked
The Read feature of the RasterSWLock register is used for
testing the locking function.
