#accumulate_attributes(pin_id) ⇒ Object

Get the chronologically last setting for the given pin's attributes

Examples:

mem.pin :tdi, size: 1
mem.pin :tdi, size: 2

my_local_attribute_hash = mem.accumulate_attributes(:tdi)
# my_local_attribute_hash now is
# {pin_id: :tdi, size: 2, bit_order: nil, format: nil, trigger: nil}
