FUJITSU SEMICONDUCTOR CONFIDENTIAL
r2.1
MB9A310 Series
DS706-00012-1v0-E
Watch Counter
The Watch counter is used for wake up from power saving mode.
Interval timer: up to 64s(Max)@ Sub Clock : 32.768kHz
External Interrupt Controller Unit
Up to 16 external vectors
Include one non-maskable interrupt(NMI)
Watch dog 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 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
Clock and Reset
[Clocks]
Five clock sources (2 ext. osc, 2 CR osc, and main PLL) that are dynamically selectable.
Main Clock
: 4MHz to 48MHz
Sub Clock
: 32.768kHz
High-speed CR Clock : 4MHz
Low-speed CR Clock : 100kHz
Main PLL Clock
[Resets]
Reset requests from INITX pins, Power on reset, Software reset, watchdog timers reset, low voltage
detector reset and clock supervisor reset.
Clock Super Visor (CSV)
Clocks generated by CR oscillators are used to supervise abnormality of the external clocks.
External OSC clock failure (clock stop) is detected, reset is asserted.
External OSC frequency anomaly is detected, interrupt or reset is asserted.
Low Voltage Detector (LVD)
This Series include 2-stage monitoring of voltage on the VCC. When the voltage falls below the voltage has
been set, Low Voltage Detector generates an interrupt or reset.
LVD1: error reporting via interrupt
LVD2: auto-reset operation
