010111: These bits provide an internal address used by the CS89712 to identify this as register

17, the Bus Control Register.

RSVD: Reserved; must be a “0” when writing to this register.

EnableIRQ: When set, the CS89712 will generate an interrupt in response to an interrupt event

(Section 2.31, “Managing Interrupts & Status Queue”). When cleared, the CS89712 will not

generate any interrupts.

After reset, if no EEPROM is found by the CS89712, then the register has the following initial state. If an EEPROM

is found, then the register’s initial value may be set by the EEPROM. See Section 2.24, “Programming the EE-

PROM”.

Reset value is: 0000 0000 0001 0111
