5.1 Cold Reset
When turning-on power, it is necessary to take a stable time of built-in regulator, built-in Flash memory and in-
ternal high-speed oscillator into consideration. TMP

has a function to insert a stable time
automatically.

Note:The above sequence is applied as well when restoring power.
Once power voltage is beyond operating voltage of power-on-reset, internal reset signal is enabled.

a function to enable low voltage detection circuit (VLTD) operation. And beyond
the release voltage of power-on-reset, kept internal reset by VLTD. When the supply voltage becomes upper
than the VLTD detection voltage, power counter starts operation, and then after tPWUP (approximately
0.9ms in fosc=9MHz) internal reset signal is released.
Power-on-reset circuit operation is referred to Section of " Power-on-reset circuit (POR) ". And low volt-
age detection circuit operation is referred to Section of " Low voltage detection circuit (VLTD) " .
