IPUIF
PUIF
(1)
The logic of each Processing Unit Status bit is the reverse of the PUIF. This provides flexibility on software
code utilizing the processing units.
PUIF: Processing Units Complete Interrupt Flag bit
PUIF is an ORed combination of IPUIF, RCCIF and CHRIF.
1 = One or more PUs completed command execution (must be cleared in software)
0 = All PUs are Idle or busy completing command execution
Unimplemented: Read as ‘0’
IPUIF: Inflate Processing Unit Complete Interrupt Flag bit
1 = IPU completed command execution (must be cleared in software)
0 = IPU is Idle or busy completing command execution
RCCIF: Rectangle Copy Graphics Processing Unit Complete Interrupt Flag bit
1 = RCCGPU completed command execution (must be cleared in software)
0 = RCCGPU is Idle or busy completing command execution
CHRIF: Character Graphics Processing Unit Complete Interrupt Flag bit
1 = CHRGPU completed command execution (must be cleared in software)
0 = CHRGPU is Idle or busy completing command execution
VMRGNIF: Vertical Blanking Interrupt Flag bit
1 = Display interface is in the vertical blanking period (must be cleared in software)
0 = Display interface is not in the vertical blanking period
HMRGNIF: Horizontal Blanking Interrupt Flag bit
1 = Display interface is in the horizontal blanking period (must be cleared in software)
0 = Display interface is not in the horizontal blanking period
CMDLVIF: Command Watermark Interrupt Flag bit
1 = Command watermark level is reached (must be cleared in software)
0 = Command watermark level is not yet reached
CMDFULIF: Command FIFO Full Interrupt Flag bit
1 = Command FIFO is full (must be cleared in software)
0 = Command FIFO is not full
CMDMPTIF: Command FIFO Empty Interrupt Flag bit
1 = Command FIFO is empty (must be cleared in software)
0 = Command FIFO is not empty
