A 3-wire slave register. After either V
CC
exceeds POA (after a POR event), a Maxim laser driver TX_POR bit is
set high (visible in 3-wire TXSTAT1 bit 7), or on a rising edge of TXD, this value is written to a Maxim laser driver
through the 3-wire interface. This register is active only during the open loop and APC loop modes. See Register
CBh for TXCTRL5 access during the dual closed-loop mode.
