Sync Method Switching Mode: When switching from master mode into TV sync mode, or from
TV sync mode into master mode, when necessary this mode should be switched into first. Even if
a transition to this mode is not made first, switching of the synchronization method is possible.
In this mode, input/output pins connected to the display unit (DU) are for input, and so pin
collision can be avoided. Also, in this mode no display operation is performed, and the internal dot
clock is stopped, so that disorder in the input dot clock has no effect on display operation.
