1284 - Data Strobe
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
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
This signal can also serve as a general-purpose I/O
signal (GPIO29) by setting bit 3 in the General-Purpose
Mode register.
Serial Clock
SCL provides the clock signal for transmitting and
receiving data through SDA.
Serial Data
SDA provides the data connection to the I
port. Data is transmitted and received through this line
according to the I
pulled HIGH by an external pull-up resistor.
