PIN NAMING CONVENTIONS

• Pin Name is composed of the multiplexed options separated by ‘/’. E.g., GPIOxxxx/SignalA/SignalB.

• The first signal shown in a pin name is the default signal. E.g., GPIOxxxx/SignalA/SignalB means the GPIO is the

default signal.

• Parenthesis ‘()’ are used to list aliases or alternate functionality for a single mux option.

• Square brackets ‘[ ]’ are used to indicate there is a Strap Option on a pin. This is always shown as the last signal

on the Pin Name.

• Signal Names appended with a numeric value indicates the Instance Number. E.g., PWM0, PWM1, etc. indicates

that PWM0 is the PWM output for PWM Instance 0, PWM1 is the PWM output for PWM Instance 1, etc. The

instance number may be omitted if there in only one instance of the IP block implemented.

Term

Definition

The ‘#’ sign at the end of a signal name indicates an active-low signal

The lowercase ‘n’ preceding a signal name indicates an active-low signal

PWR

Power

PIO

Programmable as Input, Output, Open Drain Output, Bi-directional or Bi-directional with Open

Drain Output. Configurable drive strength from 2ma to12ma.

Note:

All GPIOs have programmable drive strength options of 2ma, 4ma, 8ma and 12ma.

GPIO pin drive strength is determined by the Pin Control Register Defaults field in

the Pin Control Register 2.

I Type Input Buffer.

O-2 mA Type Buffer.

PECI

PECI Input/Output. These pins operate at the processor voltage level (VREF_VTT)

SB-TSI

SB-TSI Input/Output. These pins operate at the processor voltage level (VREF_VTT)
