NOTES:
1. tc(
φAD): one cycle of AD conversion clock. AD conversion clock can be selected from φSOURCE/2 or φSOURCE/8. φSOURCE
represents the XIN input in the frequency/2, 4 or 8 mode and internal on-chip oscillator divided by 4 in the on-chip oscillator mode or
the low-speed mode.
When the A/D conversion is executed in the frequency/2 mode, frequency/4 mode, or frequency/8 mode, set f(XIN)
≥ 500 kHz.
Relationship among AD conversion clock frequency, power source voltage, AD conversion mode and absolute accuracy.
