Other Notes
(1) Timing of power supplying
The power need to supply to VCC, VDD1, VDD2, VDD3 and AVCC at a time. While operating, must set
same voltage.
(2) Power supply noise and latch-up
In order to avoid power supply noise and latch-up, connect a bypass capacitor (more than 0.1µF)
directly between the VCC pin and VSS pin, VDD1 pin and VSS1 pin, VDD2 pin and VSS2 pin, VDD3 pin
and VSS3 pin, AVCC pin and AVSS pin using a heavy wire.
(3) When oscillation circuit stop for data slicer
Expansion register XTAL-VCO, PDC_VCO_ON,VPS_VCO_ON is set at “L”, when the data slicer is
not used, and the oscillation is stopped. When starting oscillation again, set data at the folowing
order.
(a) Set expansion register XTAL-VCO = “H”.
(b) Set expansion register PDC_VCO_ON,VPS_VCO_ON = “H”.
(c) 60 ms or more is a waiting state (stability period of internal oscillation circuit + data slice preparation).
To operate slice RAM , set expansion register XTAL_VCO = “H”. And input 4.43 MHz sub carrier
frequency clock from the FSCIN pin.
Access the memories after wating for 20 ms certainly when resuming synchronous oscillation from
the off state , and begin to input clock into the FSCIN pin.
(4) At stop mode (clock is stopped)
Set each input pins to as follows.
(a) Set M1 pin = VSS.
(b) Stop the FSCIN pin input.
(c) Set expansion register STBY0 and STBY1 = “H”.
Set all expansion registers to “L” except for the superscription register.
(5) When operation start from stand-by mode (clock is stopped)
Input FSCIN pin clock after set “L” to register STBY0 and STBY1.
At next, set expansion register as notes (3).
