LBDATA0 - LCD Bus Interface data register
The 32-bit LBDATA0 register contains the data that is transferred via the LCD
Bus Interface.
This register can be read/written in 3 different units under following names:
• LBDATA0W: 32-bit access
• LBDATA0: 16-bit access
• LBDATA0L: 8-bit access
FFFF FB70

Depending on the access to this register (byte, halfword or word), a defined
number of transfers via the external bus interface are performed:
• Byte:
• Halfword:
• Word:
When the data is split into bytes and transferred consecutively, the byte order
is as follows:

The byte is transferred via the bus interface.
The halfword is split into 2 bytes that are transferred consecutively via the
bus interface.
The word is split into 4 bytes that are transferred consecutively via the bus
interface.
