Cautions
Operation at Reset and Standby
(1) Reset signal
Reset operation is performed by setting the RST pin input level to VIL or less for 300ns or more at the supply
voltage (VDD) of 2.5V or more. (See the figure below).
Be sure to perform reset operation at power ON.
(2) Pin state at reset
Refer to the list of pin functions.
(3) Reset operation range
The reset signal causes reset inside LSI, causing return to the initial state. Though the crystal oscillation circuit is not
stopped, the internal divider circuit is stopped.
(4) Data input after reset
If 300ns or more time has elapsed after completion of reset, the register write control circuit is ready for activation.
(5) Standby mode
Set the STNBY pin to the “H” level, and LSI enters the standby mode. In this mode, all of LSI operations can be
stopped. After canceling of STNBY, the time is required till the crystal oscillation circuit becomes stable.
Digital pin output states during standby is the same as for that during reset. On the other hand, analog output pins
(FLOUT, Vref) are L outputs (Vdda/2 is output during reset).
Similarly to the case of reset, the LSI inside is reset to return to the initial state.
