VREFBUF control and status register

Type Aliases

ENVR_R

Field ENVR reader - Voltage reference buffer mode enable This bit is used to enable the voltage reference buffer mode.

ENVR_W

Field ENVR writer - Voltage reference buffer mode enable This bit is used to enable the voltage reference buffer mode.

HIZ_R

Field HIZ reader - High impedance mode This bit controls the analog switch to connect or not the VREF+ pin. Refer to for the mode descriptions depending on ENVR bit configuration.

HIZ_W

Field HIZ writer - High impedance mode This bit controls the analog switch to connect or not the VREF+ pin. Refer to for the mode descriptions depending on ENVR bit configuration.

R

Register CSR reader

VRR_R

Field VRR reader - Voltage reference buffer ready

VRS_R

Field VRS reader - Voltage reference scale These bits select the value generated by the voltage reference buffer. VRS = 000: VREFBUF0 voltage selected. VRS = 001: VREFBUF1 voltage selected. VRS = 010: VREFBUF2 voltage selected. VRS = 011: VREFBUF3 voltage selected. Others: Reserved Note: Refer to the product datasheet for each VREFBUFx voltage setting value. The software can program this bitfield only when the VREFBUF is disabled (ENVR=0).

VRS_W

Field VRS writer - Voltage reference scale These bits select the value generated by the voltage reference buffer. VRS = 000: VREFBUF0 voltage selected. VRS = 001: VREFBUF1 voltage selected. VRS = 010: VREFBUF2 voltage selected. VRS = 011: VREFBUF3 voltage selected. Others: Reserved Note: Refer to the product datasheet for each VREFBUFx voltage setting value. The software can program this bitfield only when the VREFBUF is disabled (ENVR=0).

W

Register CSR writer
