This bit is automatically cleared when the ROI bit is set and an interrupt occurs.
This setting is not allowed while the USB module is enabled.
Increments or decrements of TUN<5:0> may not change the FRC frequency in equal steps over the FRC
tuning range and may not be monotonic.
PLLEN: 96 MHz PLL Enable bit
The 96 MHz PLL must be enabled when the USB or graphics controller module is enabled. This control
bit can be overridden by the PLL96MHZ (Configuration Word 2 <11>) Configuration bit.
1 = Enable the 96 MHz PLL for USB, graphics controller or HSPLL/ECPLL/FRCPLL operation
0 = Disable the 96 MHz PLL
G1CLKSEL: Display Controller Module Clock Select bit
1 = Use the 96 MHz clock as a graphics controller module clock
0 = Use the 48 MHz clock as a graphics controller module clock
Unimplemented: Read as ‘0’
Unimplemented: Read as ‘0’
