DESCRIPTION
6, 7
SDI, SDI
I
Differential serial data inputs.
10, 11
SCI, SCI
I
Differential serial clock inputs.
15
HOSTIF_MODE
I
Host interface mode select. When HIGH, the host interface is configured for I2C mode. When
LOW, the host interface is configured for parallel port mode.
16
FIFOE/S
I
FIFO_RESET pulse control. When HIGH, the output FIFO_RESET pulse occurs on the EAV
word. When LOW, the output FIFO_RESET pulse occurs on the SAV word.
17
CRC_MODE
I
CRC_MODE enable. When HIGH, CRC_MODE is enabled. When LOW, CRC_MODE is
disabled.
18 - 20
P[7:5]
I/O
In parallel port mode, these are bits 7:5 of the host interface address/data bus. In I2C mode,
these pins must be set LOW.
21
SCL/P4
I/O
In parallel port mode, this is bit 4 of the host interface address/data bus. In I2C mode, this is the
serial clock input for the I2C port.
22
SDA/P3
I/O
In parallel port mode, this is bit 3 of the host interface address/data bus. In I2C mode, this is the
serial data pin for the I2C port.
23 - 25
A[2:0]/P[2:0]
I/O
In parallel port mode, these are bits 2:0 of the host interface address/data bus. In I2C mode,
these are input bits which define the I2C slave address for the device.
26
R/W
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 I2C mode, this
pin must be set HIGH.
