D0 - Handshake Enable - When this bit is set to 1, the handshake function is enabled.
D1 - Port Select - This bit selects which port is controlled by Handshake Channel 0. When it is set to 1,
Port 1 is selected and when it is cleared to 0, Port 4 is selected.
D2 - DMA Enable - When this bit is set to 1, the DMA function is enabled for Handshake Channel 0.
When it is cleared to 0, the DMA function is not used by the handshake channel and may be used by the
UART.
D3 - Mode - When this bit is set to 1, the "fully interlocked" mode is enabled. When it is cleared to 0, the
"strobed" mode is enabled.
D4-D7 - Deskew Counter - This 4-bit field is used to select a count value from 1 to 16 (0000-1111). This
value is the number of processor clocks used to generate the set-up and strobe when using the "strobed"
mode, or the set-up when using the "fully-interlocked" mode.
