class Control2Reg

Defined at line 474 of file ../../src/devices/power/drivers/fusb302/registers.h

CONTROL2 - Configures automated power role detection.

This register has reserved/undocumented bits. It can only be safely updated

via read/modify/write operations.

The Rev 5 datasheet refers to the entire power role detection feature as

"toggling". That term is a bit misleading, as the process can be configured

to only advertise as a Source or Sink, in which case no DRP toggling is

involved.

After reset, automated power role detection is disabled.

Public Methods

SelfType & set_tog_save_pwr (SleepDuration val)

The duration of sleep intervals between power role detection cycles.

This field is only used when `automated_dual_power_role_toggle` is set. It

configures the amount of time spent in a low-power sleep state after one

cycle of the power role detection process completes.

SleepDuration tog_save_pwr ()

The duration of sleep intervals between power role detection cycles.

This field is only used when `automated_dual_power_role_toggle` is set. It

configures the amount of time spent in a low-power sleep state after one

cycle of the power role detection process completes.

SelfType & set_tog_rd_only (typename SelfType::ValueType val)

If true, the power role detection process will ignore Ra termination.

This bit is only used when `toggle` is set. If set,

the hardware will not end the DRP toggling cycle when it detects Ra

termination (used by Audio Accessories) on its CC pins.

typename SelfType::ValueType tog_rd_only ()

If true, the power role detection process will ignore Ra termination.

This bit is only used when `toggle` is set. If set,

the hardware will not end the DRP toggling cycle when it detects Ra

termination (used by Audio Accessories) on its CC pins.

SelfType & set_wake_en (typename SelfType::ValueType val)

If true, Wake Detection is enabled.

Wake Detection only works if the `wake_detection_powered_on` field in the

`PowerReg` register is set to true.

template <, >

typename SelfType::ValueType wake_en ()

If true, Wake Detection is enabled.

Wake Detection only works if the `wake_detection_powered_on` field in the

`PowerReg` register is set to true.

Fusb302RoleDetectionMode mode ()

The behavior in a cycle of the automated power role detection process.

SelfType & set_mode (Fusb302RoleDetectionMode val)

The behavior in a cycle of the automated power role detection process.

SelfType & set_toggle (typename SelfType::ValueType val)

If true, the hardware performs automated Type C power role detection.

This bit enables the partial hardware implementation of the state machines

in usbpd2.2 4.5 "Configuration Channel (CC)". The driver sets this bit to

true to start the power role detection process. The hardware sets this bit

to false after it detects a Port Partner and establishes its own power

role.

Before setting this bit to true, the driver should configure other

registers as described in the "Toggle Functionality" section on page 7 of

the Rev 5 datasheet.
