PAC1721

bit 1:0

AUTO_REFRESH[1:0]: Configures Auto-refresh. A Refresh (any) command occurs after a conversion

cycle completes. In Single-shot Average sample mode, a Refresh (any) command occurs only after the

configured number of samples are averaged (8 samples by default). This is controlled by the

AVERAGE[2:0] bits in this register.

While Auto-refresh is enabled, manual Refresh (any) commands are ignored. Disabling the feature

allows PAC1721 to execute manual Refresh (any) commands.

When Auto-refresh is enabled, functional changes are not applied. Before modifying register values,

ensure Auto-refresh is disabled. Auto-refresh can be re-enabled afterwards.

00b = Disables Auto-refresh. Requires manual Refresh (any) commands (default).

01b = Enables Auto-refresh. Resets accumulator and accumulator count.

PAC1721 executes a Limited Refresh to move VBUS, VSENSE, VPOWER, accumulator data and

accumulator count to the I2C domain.

10b = Enables Auto-refresh. Does not reset accumulator and accumulator count.

PAC1721 executes a Limited Refresh_V to move VBUS, VSENSE, VPOWER, accumulator data and

accumulator count to the I2C domain.

11b = Reserved. Do not select this option.
