NOTES:
1.
Oscillation stabilization time is the time required for the CPU clock to return to its normal oscillation frequency after a
power-on occurs, or when Stop mode is released.
2.
The oscillation stabilization interval is determined by the basic timer (BT) input clock setting.

NOTES:
1.
Excluding quantization error, absolute accuracy values are within ± 1/2 LSB.
2.
'Conversion time' is the time required from the moment a conversion operation starts until it ends.
3.
The unit tCPU means one CPU clock period.
