1. Specified by design and not tested in production, unless otherwise specified.
2. OPA_RANGE must be set to 1 in OPAMP1_CSR.
3. Evaluated by characterization. Not tested in production.
4. Mostly I/O leakage when used in analog mode. Refer to Ilkg parameter in Table 91: I/O static characteristics.
5. R2 is the internal resistance between the OPAMP output and the OPAMP inverting input. R1 is the internal resistance
between the OPAMP inverting input and ground. PGA gain = 1 + R2/R1.
