#define LL_OPAMP_INPUT_INVERT_CONNECT_NO   (OPAMP_CSR_VMSEL_1)

OPAMP inverting input not externally connected (intended for OPAMP in mode follower or PGA without external capacitors for filtering)

#define LL_OPAMP_INPUT_INVERT_IO0   ((uint32_t)0x00000000U)

OPAMP inverting input connected to GPIO pin (valid also in PGA mode for filtering). Note: OPAMP inverting input is used with OPAMP in mode standalone or PGA with external capacitors for filtering circuit. Otherwise (OPAMP in mode follower), OPAMP inverting input is not used (not connected to GPIO pin).

#define LL_OPAMP_INPUT_INVERT_IO1   (OPAMP_CSR_VMSEL_0)

OPAMP inverting input (low leakage input) connected to GPIO pin (available only on package BGA132). Note: OPAMP inverting input is used with OPAMP in mode standalone or PGA with external capacitors for filtering circuit. Otherwise (OPAMP in mode follower), OPAMP inverting input is not used (not connected to GPIO pin).
