a. Guaranteed by design.
b. Hysteresis applies only when the Schmitt trigger is enabled or when alternate function is selected.
c. Running from internal memory, Iout = 0 mA, XCKI1 = 20 and 8 MHz, not programming flash memory.
d. Same conditions as c. (Icca1), but while programming or erasing one of the flash memory arrays.
e. CPU executing an WAIT instruction, Iout = 0 mA, XCKI1 = 20 and 8 MHz, peripherals not active.
f. Running from internal memory, Iout = 0mA, Iout = 0mA, XCKI1 = 20 MHz, XCKI2 = 32.768 kHz.
g. Iout = 0mA, XCKI1 = Vcc, X2CKI = 32.768 kHz
h. Same conditions as g. (Iccps), but in Halt mode instead of Idle mode

b. Integral (non-linearity) error; the maximum difference between the best-fit straight line reference and the actual
conversion curve.
c. Differential (non-linearity) error; the maximum difference between the best-fit stair-step reference with 1-LSB
resolution and the actual conversion curve.
d. The resistance between the device input and the internal analog input capacitance.
e. The input signal is measured across the internal capacitance.
