class Control3Reg

Defined at line 530 of file ../../src/devices/power/drivers/fusb302/registers.h

CONTROL3 - Configures the PD Protocol Layer above the BMC PHY.

After reset, all automated transmissions are disabled. The GoodCRC timeout

retry count is set to 3, but the setting is not in effect, because

re-transmissions are disabled.

Public Methods

template <, >

typename SelfType::ValueType send_hard_reset ()

Set to true by the driver to transmit a Hard Reset message.

The transmitter in the BMC PHY follows usbpd3.1 5.6.4 "Hard Reset" to

send a Hard Reset packet over the CC pin that it is currently connected to.

The hardware sets this bit to false when it's done transmitting.

SelfType & set_send_hard_reset (typename SelfType::ValueType val)

Set to true by the driver to transmit a Hard Reset message.

The transmitter in the BMC PHY follows usbpd3.1 5.6.4 "Hard Reset" to

send a Hard Reset packet over the CC pin that it is currently connected to.

The hardware sets this bit to false when it's done transmitting.

template <, >

typename SelfType::ValueType bist_tmode ()

If true, received messages are dropped after generating GoodCRC replies.

This helps implement usbpd3.1 6.4.3.2 "BIST Test Data". Enabling it helps

avoid receiver FIFO overflow when the USB PD compliance testing equipment

repeatedly sends the same data message.

typename SelfType::ValueType auto_hardreset ()

If true, automatically send HardReset messages per the USB PD spec.

typename SelfType::ValueType auto_softreset ()

If true, automatically send SoftReset messages per the USB PD spec.

This bit enables the hardware implementation of the SoftReset provision in

usbpd3.1 6.7.2 "Retry Counter" and 6.6.9.1 "tSoftReset".

typename SelfType::ValueType n_retries ()

Number of re-transmissions after timing out waiting for a GoodCRC message.

Only meaningful if `auto_retry` is true.

This field acts as the nRetryCount value in usbpd3.1 6.7.2 "Retry Counter".

usbpd3.1 6.7.7 "Counter Values and Counters" states that this value should

be set to 2.
