MB9B400A Series
Watch dog 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 the built-in low-
speed CR oscillator. Therefore, "Hardware" watchdog is active
in any low-power consumption modes except STOP mode.
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.
External Interrupt Controller Unit
Up to 16 external vectors
Include one non-maskable interrupt (NMI)
General Purpose I/O Port
This series can use its pins as general-purpose I/O ports when
they are not used for external bus or peripherals. Moreover,
the port relocate function is built in. It can set which I/O port
the peripheral function can be allocated.
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
Low-Power Consumption Mode
Three low-power consumption modes supported.
Capable of pull-up control per pin
Capable of reading pin level directly
Built-in the port relocate function
Up to 100 high-speed general-purpose I/O Ports@120pin

Debug
Serial Wire JTAG Debug Port (SWJ-DP)
Embedded Trace Macrocells (ETM) provide comprehensive
debug and trace facilities.
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.
Power Supply
VCC
= 2.7 V to 5.5 V: Correspond to the wide range
