DIP Switches and Jumpers

When the SW1 switch connects a direction control signal to ground (GND), the corresponding signal (signals) is (are) controlled as input. The direc- tion control functionality is summarized in Table 2-1.

Table 2-1. DAI_P15_GP1/DAI_P16_GP2 Direction Control Settings

SW1 Position 3	SW1 Position 4	DAI_P15_GP1 Direction
SW1 Position 5	SW1 Position 6	DAI_P16_GP2 Direction
OFF	OFF	EZ-KIT Lite is transmitter
OFF	ON	DAI_P18 sets the direction:
		0	= EZ-KIT Lite is receiver
		1	= EZ-KIT Lite is transmitter
ON	OFF	EZ-KIT Lite is receiver
ON	ON	Do not use

The source of the PDAP clock input signal, DAI_PP2_CLOCKIN, is config- ured through positions 1 and 2 of the DIP switch SW1, as illustrated in Figure 2-1 on page 2-2. The switch settings are summarized in Table 2-2.

Table 2-2. PDAP Clock-in Source Settings

SW1 Position 1	SW1 Position 2	DIA_P2_CLOCKIN Source
RX_CLK	TX_CLK
OFF	OFF	Not generated by the EZ-Extender
OFF	ON	In this configuration, the TX_CLK signal must be
		generated by one of the user configured clock
		sources.
ON	OFF	RX_CLK
ON	ON	RX_CLK; in this configuration, the RX_CLK signal is
		also routed to the TX_CLK to be used as an output.
