(12) Indeterminate outputs from ports 0 and 1 (MB90F543/F549/V540/V540G only)
During oscillation setting time of step-down circuit (during a power-on reset) after the power is turned on, the
outputs from ports 0 and 1 become following state.
If RST pin is “H”, the outputs become indeterminate.
If RST pin is “L”, the outputs become high-impedance.
Pay attention to the port output timing shown as follow.
