Function
Host interface read signal
Host interface write signal
Host interface chip select signal for
IDR1, ODR1, STR1
Host interface chip select signal for
IDR2, ODR2, STR2
Host interface address select signal
In host read access, this signal
selects the status registers (STR1,
STR2) or data registers (ODR1,
ODR2). In host write access to the
data registers (IDR1, IDR2), this
signal indicates whether the host is
writing a command or data.
Host interface data bus (single-chip
mode)
