NOTES:
1. Shown here is the valid pin state when the internal power supply voltage has stabilized after power-on.
When CNVSS = VCC, the pin state is indeterminate until the internal power supply voltage stabilizes.
* CNVSS = VCC is not available in T/V-ver..
2. P11, P12, P13, P14_0 and P14_1 pins are only in the 128-pin version.
