Tx SWITCH MATRIX FULL CONFIGURATION REGISTER

Address: 0x400C215C, Reset: 0x00000000, Name: TSWFULLCON
This register allows individual control of the Tx switches. The bit names are the same as the switch names shown in Figure 27.
Note that SWCON, Bit 16 must be set to 1 after writing to this register for the new switch settings to take effect.

Control of TR1 Switch. Connects the RCAL1 pin to the high speed TIA inverting input.
0 Switch open.
1 Switch closed.
Control of T11 Switch. Connects the DE1 pin to the high speed TIA inverting input.
0 Switch open.
1 Switch closed.
Control of T10 Switch. Connects the DE0 pin to the high speed TIA inverting input.
0 Switch open.
1 Switch closed.
Control of T9 Switch. Used in conjunction with T10 and T11.
0 Switch open. When open, the high speed TIA inverting input can be DE0 or DE1 via
T10 and T11.
1 Switch closed. Ensure T10 and T11 are open. The high speed TIA inverting input is
determined by T1, T2, T3, T4, T5, and T7.
Control of T8 Switch. Allows connection of the R
