MB9B460R Series

Multi-function Timer (Max 2 units)

The Multi-function timer is composed of the following blocks.

Minimum resolution : 6.25 ns

16-bit free-run timer × 3ch./unit

Input capture × 4ch./unit

Output compare × 6ch./unit

A/D activation compare × 6ch./unit

Waveform generator × 3ch./unit

16-bit PPG timer × 3ch./unit

The following function can be used to achieve the motor

control.

PWM signal output function

DC chopper waveform output function

Dead time function

Input capture function

A/D convertor activate function

DTIF (Motor emergency stop) interrupt function

Real-time clock (RTC)

The Real-time clock can count Year/Month/Day/Hour/Minute/

Second/A day of the week from 01 to 99.

Interrupt function with specifying date and time

(Year/Month/Day/Hour/Minute/Second/A day of the week.) is

available. This function is also available by specifying only

Year, Month, Day, Hour or Minute.

Timer interrupt function after set time or each set time.

Capable of rewriting the time with continuing the time count.

Leap year automatic count is available.

Quadrature Position/Revolution Counter (QPRC)

(Max 2 channels)

The Quadrature Position/Revolution Counter (QPRC) is used

to measure the position of the position encoder. Moreover, it is

possible to use up/down counter.

The detection edge of the three external event input pins AIN,

BIN and ZIN is configurable.

16-bit position counter

16-bit revolution counter

Two 16-bit compare registers

Dual Timer (32/16-bit Down Counter)

The Dual Timer consists of two programmable 32/16-bit down

counters.

Operation mode is selectable from the followings for each

channel.

Free-running

Periodic (=Reload)

One-shot

Watch Counter

The Watch counter is used for wake up from the low-power

consumption mode. It is possible to select the main clock, sub

clock, built-in high-speed CR clock or built-in low-speed CR

clock as the clock source.

Interval timer: up to 64s (Max) @ Sub Clock : 32.768 kHz

External Interrupt Controller Unit

External interrupt input pin: Max 16 pins

Include one non-maskable interrupt (NMI)

Watchdog Timer (2 channels)

A watchdog timer can generate interrupts or a reset when a

time-out value is reached.

This series consists of two different watchdogs, a "Hardware"

watchdog and a "Software" watchdog.

"Hardware" watchdog timer is clocked by low-speed internal

CR oscillator. Therefore, "Hardware" watchdog is active in any

power saving mode except STOP.

CRC (Cyclic Redundancy Check) Accelerator

The CRC accelerator helps a verify data transmission or

storage integrity.

CCITT CRC16 and IEEE-802.3 CRC32 are supported.

CCITT CRC16 Generator Polynomial: 0x1021

IEEE-802.3 CRC32 Generator Polynomial: 0x04C11DB7

SD Card Interface

It is possible to use the SD card that conforms to the following

standards.

Part 1 Physical Layer Specification version 3.01

Part E1 SDIO Specification version 3.00

Part A2 SD Host Controller Standard Specification version

3.00

1-bit or 4-bit data bus

Clock and Reset

[Clocks]

Five clock sources (2 external oscillators, 2 internal CR

oscillator, and Main PLL) that are dynamically selectable.

Main clock

: 4 MHz to 48 MHz

Sub Clock

: 32.768 kHz

High-speed internal CR Clock : 4 MHz

Low-speed internal CR Clock : 100 kHz

Main PLL Clock
