Description
Bit field
†
symval

Value BT.656 or Y/C Mode Raw Data Mode TSI Mode
31 RSTCH Reset channel bit. Write 1 to reset the bit, a write of 0 has no
effect.
NONE 0 No effect.
RESET 1 Resets the channel by blocking further DMA event generation
and flushing the FIFO upon completion of any pending DMAs.
Also clears the VCEN bit. All channel registers are set to their
initial values. RSTCH is autocleared after channel reset is complete.
