Handling the power supply for high-current output buffer pins (DV
CC
, DV
SS
)
Always apply power to high-current output buffer pins (DV
CC
, DV
SS
) after the digital power supply (V
CC
) is turned
on. Also when switching power off, always shut off the power supply to the high-current output buffer pins (DV
CC
,
DV
SS
) before switching off the digital power supply (V
CC
) . (There will be no problem if high-current output buffer
pins and digital power supplies are turned off and on at the same time.)
Even when high-current output buffer pins are used as general purpose ports, the power for high current output
buffer pins (DV
CC
, DV
SS
) should be applied to these pins.
Pull-up/pull-down resistance
The MB90420G/5G series does not support internal pull-up/pull-down resistance. If necessary, use external
components.
Precautions for when not using a sub clock signal.
If the X0A and X1A pins are not connected to an oscillator, apply pull-down treatment to the X0A pin and leave
the X1A pin open.
