Function Documentation

◆ Pinmux_config()

void Pinmux_config ( const Pinmux_PerCfg_t *  pinmuxCfg,
uint32_t  domainId 
)

This API configures the pinmux based on the domain.

Parameters
pinmuxCfgPointer to list of pinmux configuration array. This parameter cannot be NULL and the last entry should be initialized with PINMUX_END so that this function knows the end of configuration.
domainIdDomain ID to set pinmux configuration. Refer Pinmux_DomainId_t

◆ Pinmux_unlockMMR()

void Pinmux_unlockMMR ( uint32_t  domainId)

This API unlocks the PAD config control MMRs for the given domain.

Parameters
domainIdDomain ID to unlock the PAD config MMRs. Refer Pinmux_DomainId_t

◆ Pinmux_lockMMR()

void Pinmux_lockMMR ( uint32_t  domainId)

This API locks the PAD config control MMRs for the given domain.

Parameters
domainIdDomain ID to lock the PAD config MMRs. Refer Pinmux_DomainId_t
