5.0 Host Controller Interface Modules
Host Interface Mouse Data Out Buffer Register (HIMDO)
The HIMDO register allows the core firmware to write to the DBBOUT register while setting OBF bit in the Status register. If
an IRQ12 interrupt is enabled, it is sent. If the core interrupt on output buffer empty is enabled (OBECIE in HICTRL register
is 1), writing to HIMDO de-asserts it (low).
Location: 00 FEA8
Type:
Host Interface Keyboard/Mouse Data In Buffer Register (HIKMDI)
The HIKMDI register allows the core firmware to read to the DBBIN register while clearing IBF bit in the Status register. If
the core interrupt on IBF is enabled (IBFCIE in HICTRL register is 1). Reading from HIKMDI de-asserts it (low).
