Host Data bus [15:0]. 16-bit bi-directional data input/output bus.
HD15 is the most significant bit, while HD0 is the least significant
bit. This bus carries data, commands and status information
between the host and iDiskOnChip. The lower 8 bits are used for
8-bit register transfers. Data transfers are 16 bits wide.
Host Address bus HA[2:0]: Select the registers in the iDiskOnChip
controller.
Device I/O Write: Active low. Gates the data from the bus to
iDiskOnChip. The clocking occurs on the rising edge of the signal.
Device I/O Read: Active low. Gates the data to the bus from
iDiskOnChip. The clocking occurs on the falling edge of the
signal.
Configuration Select: Determines the device configuration as
either Master or Slave. If CSEL is negated, then the device
address is Master; if CSEL is asserted, then the device address is
Slave.
Host Chip Select 0: Active low. Selects the Command Block
registers.
Host Chip Select 1: Active low. Selects the Command Block
registers.
Host reset: Active low.
I/O Ready: Negated by iDiskOnChip to extend the host transfer
cycle (read or write) when the device is not ready to respond to a
data transfer request.
