LOSC: LOS Configuration. Defines the source for the LOSOUT pin (see Figure 15).
0 = LOS LO alarm is used as the source.
1 = (Default) LOS input pin is used as the source.
RESERVED
INV LOS: Inverts the buffered input pin LOS or LOS LO alarm to output pin LOSOUT (see Figure 15).
0 = Noninverted LOS or LOS LO alarm to LOSOUT pin.
1 = Inverted LOS or LOS LO alarm to LOSOUT pin.
ASEL: Address Select.
0 = Device address is A2h.
1 = Byte DEVICE ADDRESS in Table 02h, Register 8Ch is used as the device address.
MASK:
0 = Alarm-enable row exists at Table 01h, Registers F8h–FFh. Table 05h, Registers F8h–FFh are
empty.
1 = Alarm-enable row exists at Table 05h, Registers F8h–FFh. Table 01h, Registers F8h–FFh are
empty.
