,/* Commands */
* Registers specific to each command can be initialized in any order. "op" register (R52) should be written last so that it uses the correct register settings.
* To ensure full and correct operation it is advised to set ALL registers that a command uses. Setting registers once and performing multiple executions of commands can give incorrect operation or cause a hang sometimes. * Always setup DY before commands that use it. There is a bug where pixels may not be committed to the expected vram location. Seen with LMMV instruction. Setting DY before each use of LMMV works around this. * Always set NX,NY before using LMMV especially in P1 mode. If you don't do this then the command may hang.
