PUBUSY
PUBUSY: Processing Units are Busy Status bit
This bit is logically equivalent to the ORed combination of IPUBUSY, RCCBUSY or CHRBUSY.
1 = At least one processing unit is busy
0 = None of the processing units are busy
Unimplemented: Read as ‘0’
IPUBUSY: Inflate Processing Unit Busy Status bit
1 = IPU is busy
0 = IPU is not busy
RCCBUSY: Rectangle Copy Graphics Processing Unit Busy Status bit
1 = RCCGPU is busy
0 = RCCGPU is not busy
CHRBUSY: Character Graphics Processing Unit Busy Status bit
1 = CHRGPU is busy
0 = CHRGPU is not busy
VMRGN: Vertical Blanking Status bit
1 = Display interface is in the vertical blanking period
0 = Display interface is not in the vertical blanking period
HMRGN: Horizontal Blanking Status bit
1 = Display interface is in the horizontal blanking period
0 = Display interface is not in the horizontal blanking period
CMDLV: Command Watermark Level Status bit
The number of commands in the command FIFO changed from equal (=) to the command watermark
value to less than (<) the Command Watermark value set in CMDWMK (G1CON1<12:8>) register bits.
1 = Command in FIFO is less than the set CMDWMK value
0 = Command in FIFO is equal to or greater than the set CMDWMK value
CMDFUL: Command FIFO Full Status bit
1 = Command FIFO is full
0 = Command FIFO is not full
CMDMPT: Command FIFO Empty Status bit
1 = Command FIFO is empty
0 = Command FIFO is not empty
RCCBUSY

DPVSOE: Display Vertical Synchronization Port Enable bit
1 = V
0 = V
DPHSOE: Display Horizontal Synchronization Port Enable bit
1 = HSYNC port is enabled
0 = HSYNC port is disabled
