FACTORY DEFAULT
READ ACCESS
WRITE ACCESS
MEMORY TYPE
A 3-wire slave register. Only written if SETLOSCTL is 0. If SETLOSCTL is 1, then SETLOSH register is used. After
either V
TXSTAT1, Bit 7), or on a rising edge of TXD, this value is written to a Maxim laser driver through the 3-wire
interface.
FACTORY DEFAULT
READ ACCESS
WRITE ACCESS
MEMORY TYPE
A 3-wire slave register. The writing of this register is enabled using EXCTRL[1:0]. After either V
(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.
