blocks. ALOOP operation disconnects the RTIP/RRING inputs from the line and routes the
transmit outputs back into the receive inputs. This tests the encoders/decoders, jitter
attenuator, transmitter, receiver and timing recovery sections.
In Hardware mode, ALOOP becomes active when the LLOOP pin is floating (i.e. Midrange).
In Host mode, setting bit CR2.EALOOP = 1 commands ALOOP . Note that ALOOP overrides
all other loopback modes.
