0 = HACK as active low input
Single host request mode:
0 = Request signal is active low
1 = Request signal is active high
0 = HCS1 or HCS2 is active low
0 = HDI16 operates in single-strobe bus mode
1 = HDI16 operates in dual-strobe bus mode
0 = HDI16 internal clock frozen
1 = HDI16 operates as the host interface
0 = 16-bit mode (default) enabled
0 = Disabled
0 = HACK input pin used as a DMA transfer acknowledge input
1 = Host address 0x4 used as a host DMA transfer acknowledge input
Value reflects CVR[HC]
Value reflects CVR[HV]
0 = Data strobe is active low
