TXPORDIS: Transmit POR Disable.
0 = The 3-wire interface monitors the TXPOR bit in the laser driver’s TXSTAT1 register.
1 = The 3-wire interface ignores the TXPOR bit in the laser driver’s TXSTAT1 register.
BITS 1:0
EXCTRL[1:0]: Extra 3-Wire Control Register Selection. Used to enable/disable the 3-wire registers.
00 = SETTXEQ and SETLOSTIMER are enabled.
01 = Device mode. SETTEXEQ, SETLOSTIMER, RXCTRL3, TXCTRL2, and TXCTRL3 are disabled.
10 = SETTXEQ, SETLOSTIMER, and RXCTRL3 are enabled.
11 = SETTXEQ, SETLOSTIMER, RXCTRL3, TXCTRL2, and TXCTRL3 are enabled.

BIT 1
3WRW: Initiates a 3-wire write or read operation. The write command uses the memory address
found in the 3-wire ADDRESS register (Table 02h, Register F9h) and the data from the 3-wire WRITE
register (Table 02h, Register FAh). This bit clears itself at the completion of the write operation.
The read command uses the memory address found in the 3-wire ADDRESS register (Table 02h,
Register F9h). The address determines whether a read or write operation is to be performed. This
bit clears itself at the completion of the read operation.
0 = (Default) Reads back as 0 when the write or read operation is completed.
1 = Initiates a 3-wire write or read operation.
BIT 0
3WDIS: Disables all automatic communication across the 3-wire interface. This includes all
updates from the LUTs, APC loop, and status registers. The only 3-wire communication is with the
manual mode of operation.
0 = (Default) Automatic communication is enabled.
1 = Disables automatic communication.
