1. Overview

Realtime Clock (RTC)

The Realtime Clock (RTC) has two counting modes, calendar count mode and binary count

mode, that are controlled by the register settings.

For calendar count mode, the RTC has a 100-year calendar from 2000 to 2099 and

automatically adjusts dates for leap years.

For binary count mode, the RTC counts seconds and retains the information as a serial value.

Binary count mode can be used for calendars other than the Gregorian (Western) calendar.

See section 26, Realtime Clock (RTC) in Userʼs Manual.

Serial Communications Interface

(SCI)

The Serial Communications Interface (SCI) is configurable to five asynchronous and

synchronous serial interfaces:

 Asynchronous interfaces (UART and Asynchronous Communications Interface Adapter

(ACIA))

 8-bit clock synchronous interface

 Simple IIC (master-only)

 Simple SPI

 Smart card interface.

The smart card interface complies with the ISO/IEC 7816-3 standard for electronic signals and

transmission protocol.

Each SCI has FIFO buffers to enable continuous and full-duplex communication, and the data

transfer speed can be configured independently using an on-chip baud rate generator. See

section 34, Serial Communications Interface (SCI) in Userʼs Manual.

IrDA Interface (IrDA)

The IrDA interface sends and receives IrDA data communication waveforms in cooperation

with the SCI1 based on the IrDA (Infrared Data Association) standard 1.0. See section 35,

IrDA Interface in Userʼs Manual.

I2C bus Interface (IIC)

The 3-channel I2C bus interface (IIC) conforms with and provides a subset of the NXP I2C

(Inter-Integrated Circuit) bus interface functions. See section 36, I2C Bus Interface (IIC) in

Userʼs Manual.

Serial Peripheral Interface (SPI)

Two independent Serial Peripheral Interface (SPI) channels are capable of high-speed, full-

duplex synchronous serial communications with multiple processors and peripheral devices.

See section 38, Serial Peripheral Interface (SPI) in Userʼs Manual.

Serial Sound Interface (SSI)

The Serial Sound Interface Enhanced (SSIE) peripheral provides functionality to interface with

digital audio devices for transmitting PCM audio data over a serial bus with the MCU. The SSI

supports an audio clock frequency of up to 50 MHz, and can be operated as a slave or master

receiver, transmitter, or transceiver to suit various applications. The SSI includes 8-stage FIFO

buffers in the receiver and transmitter, and supports interrupts and DMA-driven data reception

and transmission. See section 41, Serial Sound Interface (SSI) in Userʼs Manual.

Quad Serial Peripheral Interface

(QSPI)

The Quad Serial Peripheral Interface (QSPI) is a memory controller for connecting a serial

ROM (nonvolatile memory such as a serial flash memory, serial EEPROM, or serial FeRAM)

that has an SPI-compatible interface. See section 39, Quad Serial Peripheral Interface (QSPI)

in Userʼs Manual.

Controller Area Network (CAN)

module

The Controller Area Network (CAN) module provides functionality to receive and transmit data

using a message-based protocol between multiple slaves and masters in electromagnetically-

noisy applications.

The CAN module complies with the ISO 11898-1 (CAN 2.0A/CAN 2.0B) standard and supports

up to 32 mailboxes, which can be configured for transmission or reception in normal mailbox

and FIFO modes. Both standard (11-bit) and extended (29-bit) messaging formats are

supported. See section 37, Controller Area Network (CAN) Module in Userʼs Manual.

USB 2.0 Full-Speed (USBFS) module The USB 2.0 Full-Speed (USBFS) module can operate as a host controller or device controller.

The module supports full-speed and low-speed (host controller only) transfer as defined in

Universal Serial Bus Specification 2.0. The module has an internal USB transceiver and

supports all of the transfer types defined in Universal Serial Bus Specification 2.0.

The USB has buffer memory for data transfer, providing a maximum of 10 pipes. Pipes 1 to 9

can be assigned any endpoint number based on the peripheral devices used for

communication or based on your system. See section 32, USB 2.0 Full-Speed Module

(USBFS) in Userʼs Manual.
