A 3-wire slave register. The writing of this register is enabled using EXCTRL[1:0]. After either VCC exceeds POA
(after a POR event), the Maxim laser driver TX_POR bit is set high (visible in 3W TXSTAT1, Bit 7), or on a rising
edge of TXD, this value is written to a Maxim laser driver through the 3-wire interface.
