RLength Interrupt
1. Interrupt generated when Rlength counter is MAX.
2. Read and clear Interrupt.
3. Set CLK Stop and CLK Stop level high, set IO Bit low and IODir = Output.
4. Set IO Bit High and IODir = Output.
5. Set TX/RX Bit to RX mode.
6. Reload Rlength Counter.
7. Clear CLK Stop and CLK Stop level.

1. Interrupt generated when Rlength counter is MAX.
2. Read and clear Interrupt.
3. Set CLK Stop and CLK Stop level high in Interrupt routine.
4. Set TX/RX Bit to TX mode.
5. Reload Rlength Counter.
6. Set IO Bit low and IODir = Output. Since Rlen=(MAX or 0) and TX/RX =1, IO pin is controlled by IO bit.
7. Clear CLK Stop and CLK Stop level.
Note: Data in TX fifo should not be Empty here.
