The following section focuses on the EP9312 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 EP9312 pin
signals. The second table (Table T) illustrates the pin
signal multiplexing and configuration options.
Table S is a summary of the EP9312 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
• P - Power pad
• G - Ground pad
• I - Pin is an input only
• I/O - Pin is input/output
• 4mA - Pin is a 4 mA output driver
• 8mA - Pin is an 8 mA output driver
• 12mA - Pin is an 12 mA output driver
See the text description for additional information about
bi-directional pins.
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
