MC Operating Mode:
⎯
Bits 2 to 0 are H'0: Intra macroblock processing
⎯
Bits 2 to 0 are H'1: Forward macroblock processing
⎯
Bits 2 to 0 are H'2: Reverse macroblock processing
⎯
Bits 2 to 0 are H'3: Bidirectional macroblock processing
⎯
Bits 2 to 0 are H'4: End command (When bit 2 is 1, it is regarded as the end command.)
•
Coded Block Pattern (cbp):
⎯
Bit 31: Indicates whether or not the Y0 IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
⎯
Bit 30: Indicates whether or not the Y1 IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
⎯
Bit 29: Indicates whether or not the Y2 IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
⎯
Bit 28: Indicates whether or not the Y3 IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
⎯
Bit 27: Indicates whether or not the U IDCT data exists (0: IDCT data is invalid, 1: IDCT
data is valid)
