Description
De-interlacing mode
00: no de-interlacing
01: vertical temporal median
10: majority selection algorithm (2 field)
11: majority selection algorithm (3 field)
Coefficient look-up table access mode
Disable Auto Skip
When set to zero (default) the MBS will automatically skip all
remaining operations within a task once the TASK_DONE interrupt
was generated. If enable the MBS will continue until all pipeline
stages are idle.
Skip current task
Writing a one into this bit will reset the current task and continue
with previously scheduled tasks
Soft reset
Writing a one into this bit will reset the block and all outstanding
scaling tasks
Clamp mode for IFF (affects U/V only)
Interpolation mode
Clamp mode for DFF (affects U/V only)
Decimation mode
Clamp mode for VSP
1: disables the MBS interrupts- task done and task idle.
00: each table gets written separately
01: writes to coeff table 2 are copied into table 3
10: writes to coeff table 1 are copied into table 2
11: writes to coeff table 1 are copied into table 2 and 3
0: clamp to 0-255
1: clamp to 16 - 240 (CCIR range)
00: bypass
01: reserved
10: co-sited
11: interspersed
0: clamp to 0-255
1: clamp to 16 - 240 (CCIR range)
00: bypass
01: co-sited (sub sample)
10: co-sited (low pass)
11: interspersed
0: clamp to 0-255
1: clamp to CCIR range defined by VSP_RGB (bit 6)
Used for concatenated tasks.
