Detailed Description

Represents a reference proxy to a channel operating over a bit range whose offset is specified at run time. Models ChannelConcept.

Example:

// Reference to a 2-bit channel whose offset is specified at construction time
using bits2_dynamic_ref_t = packed_dynamic_channel_reference<uint8_t,2,true> const;
 
uint16_t data=0;
bits2_dynamic_ref_t channel_ref(&data,1);
channel_ref = channel_traits<bits2_dynamic_ref_t>::max_value();     // == 3
assert(data == 6);                                                  // == (3<<1) == 6
