CONFIDENTIAL

 CRC (Cyclic Redundancy Check) Accelerator

The CRC accelerator calculates the CRC which has a heavy software processing load, and achieves a

reduction of the integrity check processing load for reception data and storage.

CCITT CRC16 and IEEE-802.3 CRC32 are supported.

 CCITT CRC16 Generator Polynomial: 0x1021

 IEEE-802.3 CRC32 Generator Polynomial: 0x04C11DB7

 Clock and Reset

[Clocks]

Selectable from five clock sources (2 external oscillators, 2 built-in CR oscillators, and Main PLL).

 Main Clock:

4 MHz to 48 MHz

 Sub Clock:

32.768 kHz

 Built-in high-speed CR Clock: 4 MHz

 Built-in low-speed CR Clock: 100 kHz

 Main PLL Clock

[Resets]

 Reset requests from INITX pin

 Power-on reset

 Software reset

 Watchdog timers reset

 Low-voltage detection reset

 Clock supervisor reset

 Clock Super Visor (CSV)

Clocks generated by built-in CR oscillators are used to supervise abnormality of the external clocks.

 When external clock failure (clock stop) is detected, reset is asserted.

 When external frequency anomaly is detected, interrupt or reset is asserted.

 Low-Voltage Detector (LVD)

This Series includes 2-stage monitoring of voltage on the VCC pins. When the voltage falls below the

voltage set, Low Voltage Detector generates an interrupt or reset.

 LVD1: error reporting via interrupt

 LVD2: auto-reset operation

 Low-Power Consumption Mode

Three Low-Power Consumption modes supported.

 SLEEP

 TIMER

 STOP

 Debug

 Serial Wire JTAG Debug Port (SWJ-DP)

 Embedded Trace Macrocells (ETM).

 Power Supply

Wide range voltage VCC = 2.7 V to 5.5 V
