Section 18 Host Interface
18.2.3
HICR is an 8-bit readable/writable register which controls host interface channel 1 and 2 interrupts
and the fast A20 gate function. HICR2 is an 8-bit readable/writable register which controls host
interface channel 3 and 4 interrupts. HICR and HICR2 are initialized to H'F8 by a reset and in
hardware standby mode.
Bits 7 to 3—Reserved: These bits cannot be modified and are always read as 1.
HICR Bits 2 and 1—Input Data Register Full Interrupt Enable 2 and 1 (IBFIE2, IBFIE1)
HICR2 Bits 2 and 1—Input Data Register Full Interrupt Enable 4 and 3 (IBFIE4, IBFIE3)
These bits enable or disable the IBF1, IBF2, IBF3, and IBF4 interrupts to the internal CPU.
