Transfer Type ( Operating Mode).
The EPPI_CTL.XFRTYPE bits select the EPPI operating mode. In receive mode
(EPPI_CTL.DIR cleared), the EPPI modes include ITU656 active video only mode,
ITU656 entire field mode, ITU656 vertical blanking only mode, and non-ITU656
mode (GP mode). For transmit mode (EPPI_CTL.DIR set), the
EPPI_CTL.XFRTYPE bits have no effect, and the EPPI (in transmit mode) is al-
ways in GP mode.
PPI Direction.
The EPPI_CTL.DIR bit selects whether the EPPI is in receive mode (if cleared) or
in transmit mode (if set).
PPI Enable.
The EPPI_CTL.EN bit enables or disables the EPPI.
