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 I
2
C 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 I
2
C 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 I
2
C mode, this is the
serial clock input for the I
2
C port.
22
SDA/P3
I/O
In parallel port mode, this is bit 3 of the host interface address/data bus. In I
2
C mode, this is the
serial data pin for the I
2
C 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 I
2
C mode,
these are input bits which define the I
2
C 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 I
2
C mode, this
pin must be set HIGH.
