IBFI1, IBFI2, IBFI3, and ERRI

The host has four interrupt requests for the slave (this LSI): IBF1, IBF2, IBF3, and ERRI. IBFI1,

IBFI2, and IBFI3 are IDR receive complete interrupts for IDR1, IDR2, and IDR3 and TWR,

respectively. IBFI3 is also used for SMIC mode and BT mode interrupt requests. The ERRI

interrupt indicates the occurrence of a special state such as an LPC reset, LPC shutdown, or

transfer cycle abort. The LMCI and LMCUI interrupts are command receive complete interrupts.
