OPAMP helper macro

group OPAMP_LL_EM_HELPER_MACRO

Defines

LL_OPAMP_COMMON_INSTANCE ( p_opamp ) (OPAMP12_COMMON)

Helper macro to select the OPAMP common instance to which is belonging the selected OPAMP instance.

Note

OPAMP common register instance can be used to set parameters common to several OPAMP instances. Refer to functions having argument “p_opamp_COMMON” as parameter.

Parameters :

  • p_opamp – OPAMP instance

Return values :

OPAMP – common instance

LL_OPAMP_IS_ENABLED_ALL_COMMON_INSTANCE ( ) ( LL_OPAMP_IsEnabled (OPAMP1) | LL_OPAMP_IsEnabled (OPAMP2))

Helper macro to check if all OPAMP instances sharing the same OPAMP common instance are disabled.

Note

This check is required by functions with setting conditioned to OPAMP state: All OPAMP instances of the OPAMP common group must be disabled. Refer to functions having argument “p_opamp_COMMON” as parameter.

Return values :

0 – All OPAMP instances sharing the same OPAMP common instance are disabled. 1: At least one OPAMP instance sharing the same OPAMP common instance is enabled
