5) RGB555 Mode
As an alternative method, a special RGB555-mode can be used which is dedicated for applications
where grabbed pictures should be processed further. In this mode, a single buffer is used instead of
a ring buffer. In addition, data is directly stored in Coral's RGB555 format in the L1-Layer (see
settings of the CBM register). This makes it possible to copy rectangular areas from the L1-layer
directly to the texture buffer or to other memory locations using the BitBlt function. Note that the
input and output frame rate should be identical if a single buffer method is used and that the lower
bits are ignored to form the RGB555 format.
