2.2.9 Flexible I/O (FlexIO)

The FlexIO is a highly configurable module providing a wide range of functionality

including:

• Emulation of a variety of serial/parallel communication protocols

• Flexible 16-bit timers with support for a variety of trigger, reset, enable and

disable conditions

• Programmable logic blocks allowing the implementation of digital logic functions

on-chip and configurable interaction of internal and external modules

• Programmable state machine for offloading basic system control functions from

CPU

2.2.10 General-Purpose Input/Output (GPIO)

The general-purpose input and output (GPIO) module is accessible via the peripheral

bus and also communicates to the processor core via a zero wait state interface

(IOPORT) for maximum pin performance. The GPIO registers support 8-bit, 16-bit or

32-bit accesses.

The device includes pins PTB0, PTB1, PTC3, PTC4, PTD4, PTD5, PTD6, and PTD7

with high current drive capability. These pins can be used to drive LED or power

MOSFETs directly. The high drive capability applies to all functions which are

multiplexed on these pins.

2.2.11 Low Power Inter-Integrated Circuit (LPI2C)

The LPI2C is a low power Inter-Integrated Circuit (I2C) module that supports an

efficient interface to an I2C bus as a master and/or a slave. The LPI2C can continue

operating in stop modes provided an appropriate clock is available and is designed for

low CPU overhead with DMA offloading of FIFO register accesses. The LPI2C

implements logic support for standard-mode, fast-mode, fast-mode plus and ultra-fast

modes of operation.

This device has three LPI2C modules. The LPI2C module provides a low power IIC

module that can operate in low power stop modes if required. Each of the three LPI2C

modules will have a 4 word (32-bit) FIFO for transmit and receive of messages.
