L64118 MPEG-2 Transport Controller with Embedded MIPS CPU (TR4101)
STROBEn/AUX_TX
1284 - Data Strobe
Input
In 1284 mode, this signal functions as STROBEn. When
set LOW, this signal indicates that valid data is present
on PDATA[7:0]. L64118 latches the data on the rising
edge of STROBEn.
Aux - Aux Port Direction
Input
In Aux mode, this signal is used to specify the direction
of the aux port if the PINACT bit (bit 4) is set in the Aux
Control register. If AUX_TX is HIGH, then the Aux port is
an output. If AUX_TX is LOW, then the Aux port is an
input.
GPIO29
Bidirectional
This signal can also serve as a general-purpose I/O
signal (GPIO29) by setting bit 3 in the General-Purpose
Mode register.
I2C-Compatible Port
These signals connect the L64118 to an external I2C device. The L64118
uses them to initialize external devices in the system that have this
interface.
SCL
Serial Clock
Bidirectional
SCL provides the clock signal for transmitting and
receiving data through SDA.
SDA
Serial Data
Bidirectional
SDA provides the data connection to the I2C-compatible
port. Data is transmitted and received through this line
according to the I2C protocol. This signal should be
pulled HIGH by an external pull-up resistor.
