The default value of this bit is set by the ZOUTSEL_tri pin. When this pin is 0, this bit and B0x15[1] are set to 0. When this pin is M, this bit is set to 0, ignored, and B0x15[1] is set to 1. When this pin is 1, this bit is set to 1 and B0x15[1] is set to 0. 0 = 85 ohm differential or 42.5 ohm single-ended 1 = 100 ohm differential or 50 ohm single-ended 0 clk0_impedance0 RW 0x0 CLK0 impedance select bit 0. The default value of this bit is set by the ZOUTSEL_tri pin. When this pin is 0, this bit and B0x15[0] are set to 0. When this pin is M, this bit is set to 0, ignored, and B0x15[0] is set to 1. When this pin is 1, this bit is set to 1 and B0x15[0] is set to 0. 0 = 85 ohm differential or 42.5 ohm single-ended 1 = 100 ohm differential or 50 ohm single-ended OUTPUT_REC_SEL_7_0 Bit Field Descriptions Bit Field Field Name Field Type Default Value Description 7 clk7_impedance1 RW 0x1 CLK7 impedance select bit 1. The default state of this bit is set by the ZOUTSEL_tri pin. When this pin is 0 or 1, this bit is set to 0 at power up and the appropriate value is set in B0x14[7]. When this pin is M, this bit is set to 1 at power up, B0x14[7] is set to 0 and ignored. 0 = See B0x14[7] 1 = 34 ohm differential or 17 ohm single-ended 6 clk6_impedance1 RW 0x1 CLK6 impedance select bit 1. The default state of this bit is set by the ZOUTSEL_tri pin. When this pin is 0 or 1, this bit is set to 0 at power up and the appropriate value is set in B0x14[6]. When this pin is M, this bit is set to 1 at power up, B0x14[6] is set to 0 and ignored. 0 = Source, see B0x14[6] 1 = 34 ohm differential or 17 ohm single-ended 5 clk5_impedance1 RW 0x1 CLK5 impedance select bit 1. The default state of this bit is set by the ZOUTSEL_tri pin. When this pin is 0 or 1, this bit is set to 0 at power up and the appropriate value is set in B0x14[5]. When this pin is M, this bit is set to 1 at power up, B0x14[5] is set to 0 and ignored. 0 = Source, see B0x14[5] 1 = 34 ohm differential or 17 ohm single-ended 4 clk4_impedance1 RW 0x1 CLK4 impedance select bit 1. The default state of this bit is set by the ZOUTSEL_tri pin. When this pin is 0 or 1, this bit is set to 0 at power up and the appropriate value is set in B0x14[4]. When this pin is M, this bit is set to 1 at power up, B0x14[4] is set to 0 and ignored. 0 = Source, see B0x14[4] 1 = 34 ohm differential or 17 ohm single-ended OUTPUT_IMPEDANCE_7_0 Bit Field Descriptions Bit Field Field Name Field Type Default Value Description |
