iMX6 IPU: SYNC field in WACK + BMA microcode

Hi,

 

iMX6Q Reference Manual lists in table 37-26 "DC template's commands description" the SYNC field sometimes with a length of 4 bits (e.g. for RD, WSTS) and sometimes with 3 bits (WACK + BMA).

 

In case of WACK, the WAVEFORM and GLUELOGIC fields are shifted one position right too.

Is this a bug in the documentation (e.g. SYNC is always 4 bits and fields in WACK are at the usual position)?  Or is this intended?
