PORT_TX_DW2 (Transmitter analog front-end config double-word 2?)

All reserved bits in this register are MBZ (must be zero). So, the register

can be safely updated without reading it first.

This register is not documented on Kaby Lake or Skylake.

Public Methods

template <, >

SelfType & set_voltage_swing_select_bit3 (typename SelfType::ValueType val)

This field must be combined with `voltage_swing_select_bits20`. The helpers

`voltage_swing_select()` and `set_voltage_swing_select()` handle that.

typename SelfType::ValueType voltage_swing_select_bit3 ()

This field must be combined with `voltage_swing_select_bits20`. The helpers

`voltage_swing_select()` and `set_voltage_swing_select()` handle that.

typename SelfType::ValueType resistance_compensation_code_scalar ()

Applied to RCOMP (resistance compensation) code.

This field adjusts the RCOMP code to get the desired output termination

resistance. This field is also named the (voltage) swing scalar.

int8_t voltage_swing_select ()

Configures the signal's peak-to-peak voltage differences.

There is an undocumented mapping between (transition and non-transition)

peak-to-peak voltage differences and values in this field. Intel's

documentation has tables mapping voltage swing and pre-emphasis levels to

field values.
