5.0 Host Controller Interface Modules
Host Interface PM n Data Out Buffer (HIPMnDO)
The HIPMnDO register allows the core firmware to write to the PM port DBBOUT register while setting the PM port OBF bit
in the Status register. If enabled, an IRQ11 (and/or SCI and/or SMI, in PC87570 Compatible mode) interrupt is sent at that
time. If the core interrupt on PM port output buffer empty is enabled, writing to HIPMnDO de-asserts it (low). If DMA on output
buffer empty is enabled, the DMA request is de-asserted on the write to HIPMnDO.
Location: Channel 1 - 00 FEAE
Type: WO
Host Interface PM n Data Out Buffer with SCI (HIPMnDOC)
The HIPMnDOC register has the same function as the HIPMnDO register. In addition, it generates an SCI interrupt when
OBF is set and hardware SCI generation is enabled.
Location: Channel 1 - 00 FEB2
Type: WO
Host Interface PM n Data Out Buffer with SMI (HIPMnDOM)
The HIPMnDOM register has the same function as the HIPMnDO register. In addition, it generates an SMI interrupt when
OBF is set and hardware SMI generation is enabled.
Location: Channel 1 - 00 FEB4
Type: WO
