Register 27: ADC Test Mode Loopback (ADCTMLB), offset 0x100
This register provides loopback operation within the digital logic of the ADC, which can be useful in
debugging software without having to provide actual analog stimulus. This test mode is entered by
writing a value of 0x0000.0001 to this register. When data is read from the FIFO in loopback mode,
the read-only portion of this register is returned.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
Continuous sample counter that is initialized to 0 and counts each
sample as it processed. This helps provide a unique value for the data
received.
When set, indicates that this is a continuation sample. For example if
two sequencers were to run back-to-back, this indicates that the
controller kept continuously sampling at full rate.
When set, indicates that this is a differential sample.
When set, indicates that this is a temperature sensor sample.
Indicates which analog input is to be sampled.
