LBDATAR0 - LCD Bus Interface data register
The LBDATAR0 register is read-only. It contains the data of the last previous
read transfer via the LCD Bus Interface. Reading this register does not start a
new read transfer on the LCD Bus Interface.
This register can be read/written in 3 different units under following names:
• LBDATAR0W: 32-bit access
• LBDATAR0: 16-bit access
• LBDATAR0L: 8-bit access

This register can be read to obtain data that was transferred during a previous
read operation to the LBDATA0 register—without initiating a further LCD bus
transfer.
Reading the LBDATAR0 register does not change the status of the
LBCTL0.BYF0 and LBCTL0.TPF0 flags.
