11.7.3.4 LCD Disable Done Interrupt Mask (LDM)
The LCD disable done interrupt mask (LDM) bit is used to mask or enable interrupt requests that
are asserted after the LCD is disabled and the frame currently being output to the pins has
completed. When LDM=0, the interrupt is enabled, and whenever the LCD disable done (LDD)
status bit within the LCD status register (LCSR) is set (one), an interrupt request is made to the
interrupt controller. When LDM=1, the interrupt is masked and the state of the LDD status bit is
ignored by the interrupt controller. Note that programming LDM=1 does not affect the current state
