I Differential serial data inputs.
I Differential serial clock inputs.
I Host interface mode select. When HIGH, the host interface is configured for I≤C mode. When
LOW, the host interface is configured for parallel port mode.
I FIFO_RESET pulse control. When HIGH, the output FIFO_RESET pulse occu rs on the EAV
word. When LOW, the output FIFO_RESET pulse occurs on the SAV word.
I CRC_MODE enable. When HIGH, CRC_MODE is enabled. When LOW, CRC_MODE is
disabled.
I/O In parallel port mode, these are bits 7:5 of the host interface address/data bus. In I≤C mode,
these pins must be set LOW.
I/O In parallel port mode, this is bit 4 of the host interface address/data bus. In I≤C mode, this is the
serial clock input for the I≤C port.
I/O In parallel port mode, this is bit 3 of the host interface address/data bus. In I≤C mode, this is the
serial data pin for the I≤C port.
I/O In parallel port mode, these are bits 2:0 of the host interface address/data bus. In I≤C mode,
these are input bits which define the I≤C slave address for the device.
I Parallel port read/write control. When HIGH, the parallel port is configured as an output (read
mode). When LOW, the parallel port is configured as an input (write mode). In I≤C mode, this
pin must be set HIGH.
