POWER-ON RESET
The MB582A and MB583A must be reset when the power is turned on. There are two methods available for resetting
each device at power-on. Select the best method.
(1) Apply a reset to the device at power-on, then cancel the reset 50 ms after the V
CC
and AV
CC
have reached 5 V
or input a reset pulse with a width of 50 ms after they reached 5 V. Note that a stable reference clock signal
(REFCLK or PICLK) must be input before the reset is canceled. (See the diagram below.)
This method eliminates the need for connecting an external capacitor to the TIMER pin as described in method
(2).
Be sure to leave the TIMER pin open when not in use.
