0 - GPIO Port H used for IDE
1 - GPIO Port H used for GPIO
HDLC3 clock in. This bit has no effect unless HC3EN is 1.
1 = pin EGPIO[3] is an input and drives an external HDLC
clock to UART3.
0 = pin EGPIO[3] is an output driven by UART3.
HDLC3 clock enable.
1 = pin EGPIO[3] is used to for an HDLC clock with
UART3.
0 = pin EGPIO[3] is not used.
HDLC1 clock in. This bit has no effect unless HC3EN is 0
and HC1EN is 1.
1 = pin EGPIO[3] is an input and drives an external HDLC
clock to UART1.
0 = pin EGPIO[3] is an output driven by UART1.
HDLC1 clock enable. This bit has no effect unless HC3EN
is 0.
1 = pin EGPIO[3] is used for an HDLC clock with UART1.
0 = pin EGPIO[3] is not used.
Touchscreen controller inactive.
1 - Touchscreen controller to inactive state,
0 - Touchscreen controller active.
To use the ADC converter independent of the Touch
screen controller, the Touchscreen controller must be
enabled and set inactive. The ADC can then be operated
using the direct access registers. The TIN bit does not
affect the ADC power state. ADC power down is directly
controlled by the ADCPD bit.
UART1 Enable.
1 - UART1 baud rate clock is active.
0 - UART1 clock is off.
External Video Clock.
1 - Raster engine uses external pixel clock and the SPCLK
pin is configured as an input,
0 - Raster engine uses internal pixel clock and the SPCLK
pin is configured as an output.
UART2 Enable.
1 - UART2 baud rate clock is active.
0 - UART2 clock is off.
