packed_channel_reference
[Models]


Detailed Description

Represents a reference proxy to a channel operating over a bit range whose offset is fixed at compile time. Models ChannelConcept Example:.

// Reference to a 2-bit channel starting at bit 1 (i.e. the second bit)
typedef const packed_channel_reference<uint16_t,1,2,true> bits2_1_ref_t;

uint16_t data=0;
bits2_1_ref_t channel_ref(&data);
channel_ref = channel_traits<bits2_1_ref_t>::max_value();   // == 3
assert(data == 6);                                          // == 3<<1 == 6
