Timers

Programmable pulse

generator (PPG)

 (4 bits × 4 groups) × 2 units

 Pulse output with the MTU or TPU output as a trigger

 Maximum of 32 pulse-output possible

Realtime clock (RTCd)*1

 Clock sources: Main clock, sub clock

 Selection of the 32-bit binary count in time count/second unit possible

 Clock and calendar functions

 Interrupt sources: Alarm interrupt, periodic interrupt, and carry interrupt

 Battery backup operation

 Time capture function (up to 3 pins)

 Event linking by the ELC

Communication

function

USB 2.0 FS host/

function module (USBb)

 Includes a UDC (USB Device Controller) and transceiver for USB 2.0 FS

 Up to two ports

 Compliance with the USB 2.0 specification

 Transfer rate: Full speed (12 Mbps), low speed (1.5 Mbps) (host only)

 Both self-powered mode and bus-powered mode are supported

 OTG (On the Go) operation is possible (low-speed is not supported)

 Incorporates 2 Kbytes of RAM as a transfer buffer

 External pull-up and pull-down resistors are not required

Serial communications

interfaces

(SCIk, SCIm, SCIh)

 13 channels (SCIk: 10 channels + SCIh: 1 channel + SCIm: 2 channels)

 SCIk, SCIh, SCIm

Serial communications modes: Asynchronous, clock synchronous, and smart-card

interface

Multi-processor function

On-chip baud rate generator allows selection of the desired bit rate

Choice of LSB-first or MSB-first transfer

Start-bit detection: Level or edge detection is selectable.

Simple I2C

Simple SPI

9-bit transfer mode

Bit rate modulation

Double-speed mode

 SCIk, SCIh

Average transfer rate clock can be input from TMR timers for SCI5, SCI6, and SCI12

Event linking by the ELC (only on channel 5)

 SCIh

Supports the serial communications protocol, which contains the start frame and

information frame

Supports the LIN format

 SCIm

Data can be transmitted or received in sequence by the 16-byte FIFO buffers of the

transmission and reception unit

 SCIk, SCIm

Data match detection

Adjustment of the timing of sampling of the RXD signals
