MT312 Tuner Control  
Pin 45 = DATA2, this is a transparent, bi-directional connection to the primary DATA1.  
Pin 44 = CLK2, this is a transparent, bi-directional connection to the primary CLK1.  
If B6 = 0 then: GPP DIR[2:0] denes the input/output conditions of the GPP pins and:  
If a pin[n] is dened as output then:  
GPP PIN[n] high forces GPP[n] pin high  
GPP PIN[n] low forces GPP[n] pin low  
If a pin[n] is dened as input then:  
GPP[n] pin high sets bit GPP PIN[n] high  
GPP[n] pin low sets bit GPP PIN[n ] low  
Allocation of GPP PIN[2:0] is:  
GPP PIN[2] = DiSEqCv2.2 input, 3 wire bus Enable or can be used for any other application  
GPP PIN[1] = DATA2 or 3 wire bus Data  
GPP PIN[0] = CLK2 or 3 wire bus Clock  
The register default state of 20 hex allows the GPP[2] pin to be used for the 3 wire bus Enable line and to be  
kept low at all times, except when programming the Synthesiser.  
When GPP[2] pin is used for DiSEqCv2.2 input, the GPP CTRL register will need to be set to zero after  
every full reset to make GPP[2] an input.
