BIT 7 BIT 0
A 3-wire slave register. Only written if SETLOSCTL is 0. If SETLOSCTL is 1, then the SETLOSH register is used. 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.
