Interrupt Disable (ID): Disables this device from generating PCI line based 
interrupts. This bit does not have any effect on MSI operation.

Bus Master Enable (BME): Controls the HECI host controller's ability to act as 
a system memory master for data transfers. When this bit is cleared, HECI bus 
master activity stops and any active DMA engines return to an idle condition. 
This bit is made visible to firmware through the H_PCI_CSR register, and 
changes to this bit may be configured by the H_PCI_CSR register to generate an 
ME MSI.
0 = HECI is blocked from generating MSI to the host processor.
Note that this bit does not block HECI accesses to ME-UMA, i.e. writes or reads 
to the host and ME circular buffers through the read window and write window 
registers still cause ME backbone transactions to ME-UMA.

Memory Space Enable (MSE): Controls access to the HECI host controller’s 
memory mapped register space.
