Note
Look-Up Table Data Bits [3:0]
This register is used to read/write the RGB Look-Up Tables. This register is an aperture
into the three 16-position Look-Up Tables. The Look-Up Table Address Register
(REG[16h]) selects which Look-Up Table position is accessible. See REG[16h] Look-Up
Table Bank Select Register on page 66.
GPIO[4:0] Pin IO Configuration
These bits determine the direction of the GPIO[4:0] pins.
When GPIOn Pin IO Configuration bit = 0, the corresponding GPIOn pin is configured as
an input. The input can be read at the GPIOn Status/Control Register bit. See REG[19h]
below.
When GPIOn Pin IO Configuration bit = 1, the corresponding GPIOn pin is configured as
an output. The output can be controlled by writing the GPIOn Status/Control Register bit.
GPIO[4:0] Status
When the GPIOn pin is configured as an input, the corresponding GPIO Status bit is used
to read the pin input. See REG[18h] above.
When the GPIOn pin is configured as an output, the corresponding GPIO Status bit is used
to control the pin output.
These bits have no effect when the GPIOn pin is configured for a specific function (i.e.
as FPDAT[11:8] for TFT/MD-TFD operation). All unused GPIO pins must be tied to
