Consider ignoring indexer if the specified value is zero and the length of the register is equal to one

Specifically in this generation step:

reflex-generator/interface/Device.tt

Line 535 in de85b82

var memberIndexer = member.Value.Offset.HasValue ? $"[{member.Value.Offset}]" : string.Empty;

The advantage would be allowing reusable payloadSpec definitions shared across registers where one is single value and the other is array.

For example, in the below, StartPulseTrain could be defined by reusing the definition in StartPulse:

  StartPulse:
    address: 37
    type: U16
    access: Write
    description: Starts a single pulse on the specified digital output line.
    payloadSpec: &pulse
      DigitalOutput:
        offset: 0
        mask: 0xC00
        maskType: PwmOutput
        description: Specifies the digital output line on which to run each pulse.
      PulseWidth:
        offset: 0
        mask: 0x3FF
        interfaceType: ushort
        description: Specifies the duration in milliseconds that each pulse is HIGH.
  StartPulseTrain:
    address: 38
    type: U16
    length: 2
    access: Write
    description: Starts a pulse train on the specified digital output line.
    payloadSpec:
      <<: *pulse
      Frequency:
        offset: 1
        mask: 0xFF00
        minValue: 1
        maxValue: 255
        defaultValue: 1
        interfaceType: byte
        description: Specifies the rate in Hz of the pulses in the PWM pulse train.
      PulseCount:
        offset: 1
        mask: 0xFF
        interfaceType: byte
        description: Specifies the number of pulses in the PWM pulse train. A value of zero signifies an infinite pulse train.
