4.3.2.2
Read: Anytime. Write: Never, writes to this register have no effect.
If the LCD frontplane driver of an associated I/O pin is enabled (and LCD module is enabled) or the
associated ATDDIEN0 bit is set to 0 (digital input buffer is disabled), a read returns a 1.
If the LCD frontplane driver of an associated I/O pin is disabled (or LCD module is disabled) and the
associated ATDDIEN0 bit is set to 1 (digital input buffer is enabled), a read returns the status of the
associated pin.
4.3.2.3
Read: Anytime. Write: Anytime.
This register configures port pins PL[7:0] as either input or output.
If a LCD frontplane driver is enabled (and LCD module is enabled), it outputs an analog signal to the
corresponding pin and the associated Data Direction Register bit has no effect. If a LCD frontplane driver
is disabled (or LCD module is disabled), the corresponding Data Direction Register bit reverts to control
the I/O direction of the associated pin.
