 Quadrature Position/Revolution Counter (QPRC)

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 Low Power Consumption mode.

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

 External Interrupt Controller Unit

 Up to 6 external interrupt input pin

 Include one non-maskable interrupt (NMI)

 Watchdog Timer (2channels)

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 RTC and STOP and Deep stand-by RTC and Deep

stand-by 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
