10. Internal DC Regulator
Internal DC regulator stops in stop mode. When the regulator stops owing to the increase of inner leakage
current (ICCH) in stop mode, malfunction caused by noise or any troubles about power supply in normal
operation, the internal 3 V power supply voltage may decrease less than the warranty range for normal
operation. So when using the internal regulator and stop mode with 5 V power supply, never fail to support
externally so that 3 V power supply voltage might not decrease. However, even in such a case, the internal
regulator can be restarted by inputting the reset procedure. (In this case, set the reset to “L” level within the
oscillation stabilizing waiting time.)
11. Pin Condition at Turning on the Power Supply
The pin condition at turning on the power supply is unstable. The circuit starts being initialized after turning
on the power supply and then starting oscillation and then the operation of the internal regulator becomes
stable. So it takes about 42 ms for the pin to be initialized from the oscillation starting at the source oscillation
12.5 MHz. Take care that the pin condition may be output condition at initial unstable condition.
(With the MB91101A, however, initalization can be achieved in less than about 42 ms after turning on the
internal power supply by maintaining the RST pin at "L" level.)
12. Source Oscillation Input at Turning on the Power Supply
At turning on the power supply, never fail to input the clock before cancellation of the oscillation stabilizing
waiting.
13. Hardware Stand-by at Turning on the Power Supply
When turning on the power supply with the HST pin being set to “L” level, the hardware does not stand by.
However the HST pin becomes available after the reset cancellation, the HST pin must once be back to “H”
level.
14. Power on Reset
Make sure to make power on reset at turning on the power supply or returning on the power supply when
the power supply voltage is below the warranty range for normal operation.
15. Notes on during operation of PLL clock mode
If the PLL clock mode is selected, the microcontroller attempt to be working with the self oscillating circuit
evevn when there is no external oscillator or external clock input is stopped. Performance of this operation,
however, cannot be guaranteed.
16. Watchdog timer function
The watchdog timer supported by the FR family monitors the program that performs the reset delay operation
for a specified time. If the program hangs up and the reset delay operation is not performed, the watchdog
timer resets the CPU. Therefore, once the watchdog timer is enabled, operation continues until the CPU is
reset.
As an exception, a reset delay automatically occurs if the CPU stops program execution.
