* Like _PICK_EVEN(), but supports 2 ranges of evenly spaced address offsets.
|
|
* @__c_index corresponds to the index in which the second range starts to be

|
|
* @__c_index), while the second range is used for [ @__c_index, ... ). Example:
|
|
*
|
|
* #define _FOO_A 0xf000
|
|
* #define _FOO_B 0xf004
|
|
* #define _FOO_C 0xf008

|
* _SUPER_FOO_A, _SUPER_FOO_B))
|
|
*
|
|
* This expands to:
|
|
* 0: 0xf000,
