BIT 7 BIT 0
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.

BIT 7
TEMP_UPD:
0 = Default 3-wire operation.
1 = All the control registers (from Register 0Eh–E8h and Register EAh) are written every temperature
conversion.
BIT 6
EN_3945:
0 = Bytes associated with the MAX3945 are not sent on the 3-wire bus.
1 = Bytes associated with the MAX3945 are transmitted on the 3-wire bus on power-up (after V
CC
crosses the VCC LO alarm).
BIT 5
RSTRT_3710:
0 = TXINLOS (TXSTAT1 register) does not affect system restart.
1 = When TXINLOS (TXSTAT1 register) is set, Register E9h (TXCTRL6) is written to MAX3710
periodically every t
RR
.
