EP9307
ARM9 SOC with Ethernet, USB, Display and Touchscreen
The following section focuses on the EP9307 pin signals
from two viewpoints - the pin usage and pad
characteristics, and the pin multiplexing usage. The first
table (
Table S
) is a summary of all the EP9307 pin
signals. The second table (
Table T
) illustrates the pin
signal multiplexing and configuration options.
Table S
is a summary of the EP9307 pin signals, which
illustrates the pad type and pad pull type (if any). The
symbols used in the table are defined as follows. (Note: A
blank box means Not Applicable (NA) or, for Pull Type,
No Pull (NP).)
Under the Pad Type column:
A - Analog pad
See the text description for additional information about
bi-directional pins.
P - Power pad
G - Ground pad
I - Pin is an input only
I/O - Pin is input/output
4mA - Pin is a 4mA output driver
8mA - Pin is an 8mA output driver
12mA - Pin is an 12mA output driver
Under the Pull Type Column:
PU - Resistor is a pull up to the RVDD supply
PD - Resistor is a pull down to the RGND supply
.
