EPD: Enable Presence Detect Interrupt. If this bit is a 1, and the Presence Detect flag is set, then the

INTR pin will become active whenever a 1-Wire Reset is sent and an appropriate amount of time has

passed for a presence detect pulse to have occurred.

IAS: INTR Active State. This bit determines the active state for the INTR pin. If this bit is a 1, the INTR

pin is active high; if it is a 0, the INTR pin is active low.

EBTE: Enable Transmit Buffer Empty Interrupt. If this bit is a 1, and the Transmit Buffer Empty flag is

set, then the INTR pin will become active.

ETMT: Enable Transmit Shift Register Empty Interrupt. If this bit is a 1, and the Transmit Shift Register

Empty flag is set, then the INTR pin will become active.

ERBF: Enable Receive Buffer Full Interrupt. If this bit is a 1, and the Receive Buffer Full flag is set, then

the INTR pin will become active.

ESINT: Enable Slave Interrupt. If this bit is a 1, and the Slave Interrupt flag is set, then the INTR pin will

become active.

ENBSY: Enable Not Busy Interrupt. If this bit is a 1, and the Not Busy flag is set, then the INTR pin will

become active.

DQOE: DQ Output Enable. This bit acts as a control select for the DQ bus. When set to 0 (default), the

bus is controlled by the 1-Wire Master as normal. When set to 1, the DQ0 bit located in the Command

Register controls the state of the bus directly. This bit defaults to 0 on power-up or reset and should be

left 0 unless the user desires to control the bus manually through the DQ0 bit.
