Electrical Characteristics
Table A-16. ATD Conversion Performance 5V range
Conditions are shown in Table A-4. unless otherwise noted. V_REF = V_RH - V_RL = 5.12V. f_ATDCLK = 8.0MHz
The values are tested to be valid with no PortAD output drivers switching simultaneous with conversions.

1. The 8-bit and 10-bit mode operation is structurally tested in production test. Absolute values are tested in 12-bit mode.
2. These values include the quantization error which is inherently 1/2 count for any A/D converter.
